Display version number in update-core.php `Re-install Now` button

[afragen]

Currently in the update-core.php page the Re-install Now button only presents the information about which version is being re-installed in the text above the button.

Placing the version inside the button would make this more clear and might allow for the removal of the description string.

Moving to commit per today's #core-auto-updates meeting.

This looks good, my only concern here is that if we switch these buttons to sentence case, they don't match the rest of the capitalized buttons on the screen still using Title Case: "Update Plugins", "Update Themes", "Update Translations". Would someone be up for creating a ticket to update those buttons for consistency? Otherwise, that can be included in a general ticket: #49616.

There are also similar buttons on plugin installation screens: "Install Now", "Cannot Install", "Update Now", "Cannot Update", "Install Update Now" that should probably be converted to sentence case too in a future release.

There is one more reference to "Update Now" in Site Health that show be "Update now" after this change, I can adjust that on commit.

In 49984:

Upgrade/Install: Display version number on the "Re-install now" button on WordPress Updates screen.

This makes the button label more clear and allows for removing unnecessary description.

Props afragen, audrasjb.
Fixes #51774.
