Site editor theme export: remove site specific details

[jffng]

Currently when you use the Site Editor's theme export functionality, there are some block attributes that are specific to the site, including:

• refs id on the Navigation block
• queryId on the query block

It would be better to not include these attributes on theme export, since they do not have any use / may cause incorrect behavior if the theme is installed on a different site.

See ​https://github.com/WordPress/gutenberg/issues/42730 for more context.

Thanks so much for working on this, it looks great!

Do you think we should also remove the id attributes from the image and cover blocks? Both these blocks also include wp-image-[id] classes, which I think would be good to remove at the same time.

Good idea, done in ​4def221. I also added a filter for the media & text block.

Lets remove taxQuery?
