Our CI workflows generally cache `**/node_modules` (note the glob, it
caches all transitive node_module directories) to speed up startup for
new jobs that don't change any dependencies. However it seems like one
of our caches got into a weird state (not sure how it happened) where
the `build` directory (used in various other scripts as the directory
for compiled React packages) would contain a `node_modules` directory as
well. This made sizebot size change messages very big since it would try
to compare every single file in `build/node_modules`.
The fix is to ensure we always clean the `build` directory before doing
anything with it. We can also delete that one problematic cache but this
PR is a little more resilient to other weird behavior with that
directory.
I happened to notice some jobs on main get canceled if another PR landed
before the prior commit on main had finished running CI. This is not
great for difftrain because the commit artifacts job relies on the CI
jobs on main finishing before it triggers. This would lead to commits
being skipped on DiffTrain which is not great for provenance since we
want it to be a 1:1 sync.

Thanks for submitting a pull request!
We appreciate you spending the time to work on these changes. Please
provide enough information so that others can review your pull request.
The three fields below are mandatory.
Before submitting a pull request, please make sure the following is
done:
1. Fork [the repository](https://github.com/facebook/react) and create
your branch from `main`.
2. Run `yarn` in the repository root.
3. If you've fixed a bug or added code that should be tested, add tests!
4. Ensure the test suite passes (`yarn test`). Tip: `yarn test --watch
TestName` is helpful in development.
5. Run `yarn test --prod` to test in the production environment. It
supports the same options as `yarn test`.
6. If you need a debugger, run `yarn test --debug --watch TestName`,
open `chrome://inspect`, and press "Inspect".
7. Format your code with
[prettier](https://github.com/prettier/prettier) (`yarn prettier`).
8. Make sure your code lints (`yarn lint`). Tip: `yarn linc` to only
check changed files.
9. Run the [Flow](https://flowtype.org/) type checks (`yarn flow`).

## Summary
<!--
Explain the **motivation** for making this change. What existing problem
does the pull request solve?
-->
In the shared_lint,
for the first Prettier job, use `${{ runner.arch }}-${{ runner.os
}}-modules-${{ hashFiles('yarn.lock') }}` as the cache key.
For the following jobs, use `${{ runner.arch }}-${{ runner.os
}}-modules-${{ hashFiles('**/yarn.lock') }}` as the cache key.
Some of the jobs do not hit the cache if the hash does not match.
## How did you test this change?
<!--
Demonstrate the code is solid. Example: The exact commands you ran and
their output, screenshots / videos if the pull request changes the user
interface.
How exactly did you verify that your PR solves the issue you wanted to
solve?
If you leave this empty, your PR will very likely be closed.

I run [act](https://github.com/nektos/act) locally to test it.
actions/cache has a default timeout of 10 minutes. Occasionally the
cache service download gets stuck and it waits this amount of time
before proceeding like it was a cache miss.
10 minutes is way too long so let's shorten this to a minute.
