Same as https://github.com/astral-sh/ty/pull/1391:
> Last time I ran this script, due to what I assume was a `npm` version
mismatch, the `package-lock.json` file was updated while running `npm
install` in the `schemastore`. Due to the use of `git commit -a`, it was
accidentally included in the commit for the semi-automated schemastore
PR. The solution here is to only add the actual file that we want to
commit.
How was this working for anyone else? The `prettier` path did not exist
on my machine. Also added `--force` to the push because otherwise you
can't re-run the script for a given Ruff commit.
## Summary
SchemaStore now depends on some Prettier plugins, so we need to install
Prettier and its plugins as part of the project (rather than relying on
a global install).
## Test Plan
Ran the script!
* Add a script to update the schemastore
Hacked this together, it clones astral-sh/schemastore, updated the schema and pushes the changes
to a new branch tagged with the ruff git hash. You can see the URL to create the PR
to schemastore in the CLI. The script is separated into three blocks so you can rerun
the schema generation in the middle before committing.
* Use tempdir for schemastore
* Add comments
