Update WordPress packages for 5.7 Beta 1

[noisysocks]

The @wordpress npm packages need to be updated prior to Beta 1. I'll do this in two parts so that there's less rushing in the days prior to Beta 1:

1. Update packages as of Gutenberg 9.8 on Jan 20.
2. Update packages as of Gutenberg 9.9 on Feb 1.

Update WordPress packages ahead of WP 5.7.

To do:

• [ ] Unsure about whether to port i18n change in client-assets.php. Have asked in ​https://github.com/WordPress/gutenberg/pull/28279.
• [ ] Need ​https://github.com/constancecchen/object-fit-polyfill to publish src to npm so that we can vendor it.
• [ ] Re-check the client-assets.php diff for changes I may have missed.
• [ ] Run Gutenberg E2E tests against this branch.

Spoke to @ajlende about this. He's going to open a PR which adds src to the npm package.

Fix failing font-size-picker.test.js test.

This is the only remaining failure I get when I run Gutenberg E2E tests against this branch:

  ● Font Size Picker › should apply a custom font size using the font size input

    expect(received).toMatchSnapshot()

    Snapshot name: `Font Size Picker should apply a custom font size using the font size input 1`

    - Snapshot  - 1
    + Received  + 1

    - 
    + 
      <p style="font-size:23px">Paragraph to be made "small"</p>
      

      76 | 		// Ensure content matches snapshot.
      77 | 		const content = await getEditedPostContent();
    > 78 | 		expect( content ).toMatchSnapshot();
         | 		                  ^
      79 | 	} );
      80 | 
      81 | 	it( 'should reset a named font size using the reset button', async () => {

This seemingly relates to ​https://github.com/WordPress/gutenberg/pull/27083. I'm having a hard time figuring out if px should be appended in Core or if that's a FSE-related change that should remain in the plugin only. Do you know, @jorgefilipecosta ? If it should be changed in Core, where should that change happen?

Unsure about whether to port i18n change in client-assets.php. Have asked in WordPress/gutenberg#28279.

Preference is to land Core-46089 as a proper fix for this. Will land the workaround that Gutenberg has if that can't be done for 5.7.

It looks like in the plugin it sets the attribute to 23px because there is a px in editorSettings.__experimentalFeatures.global.typography.fontSizes. In my mind it makes sense to leave this as is (no px) because we do not want __experimentalFeatures to be added to Core.

Only one small issue in the editor: typing /freeform doesn't bring up the Classic block as expected (this works in Gutenberg 9.8)

Hmm... this seems okay to me?

Editor: Update @wordpress npm packages

Update @wordpress npm packages to the latest published versions. This means that
the block editor includes functionality that exists in Gutenberg 9.8.

Replying to noisysocks:

1. Update packages as of Gutenberg 9.8 on Jan 20.

[50048] does this.

2. Update packages as of Gutenberg 9.9 on Feb 1.

This is next. Waiting for Gutenberg 9.9 RC to be published at the end of this week.

Editor: Move blocks/classic -> blocks/freeform

Moves src/wp-includes/blocks/classic to src/wp-includes/blocks/freeform. This
reflects the 'classic' block being renamed to 'freeform'.

Follows [50048].
See #52334.

Update WordPress packages ahead of WP 5.7. This is everything that is included in Gutenberg 9.9.

I have checked git diff release/9.8 release/9.9 lib for changes and ran Gutenberg E2E tests against Core.
