Needed by the webpack 5 upgrade in #26382, as the 7.12 version includes fixes for Babel helper ESM imports from babel/babel#10853.

There is some tweaking necessary to the lock file as explained in the comment.

Let's add CHANGELOG entries for @wordpress/babel-plugin-default and @wordpress/scripts to let people know (there should be very similar entries already to copy and edit).

The linting CI tasks reports some pre-existing errors:

[1] /home/runner/work/gutenberg/gutenberg/packages/editor/src/components/post-saved-state/index.js
[1]   79:26  error  ["_links"] is better written in dot notation  dot-notation
[1] 
[1] /home/runner/work/gutenberg/gutenberg/packages/editor/src/components/post-trash/check.js
[1]   21:31  error  ["rest_base"] is better written in dot notation  dot-notation

I'm confused about this: the master branch checks are green, and I'm not aware of any changes introduced in this PR that would make the linter report new errors.

BTW I also had to upgrade browserslist from 4.14.0 to 4.15.0 to avoid Babel packages duplicating it. @babel/preset-env depends on core-js-compat that depends on browserslist@^4.15.0.

Those two linting errors are surprising but we can fix or disable them to move forward 🤷‍♂️

It's very close to merge. Actually we only need to make CI happy and you can ship 🚢

I'm working on this. A little trouble is that postType?.[ 'rest_base' ] complains about dot-notation, but postType?.rest_base triggers the camelcase (identifier not in camel case) rule for a change 🤷‍♂️

Fixed in the latest commit.

Both violations are in places that use optional chaining. That makes me think that it has something to do with upgraded @babel/parser and how ESLint interacts with it through the babel-eslint module.
