The CLA signature bot will check the authors of each PR to ensure they
have all signed the CLA. If any authors still need to sign the CLA, it
will leave a comment explaining how it can be signed, and will check
back upon each comment to see if it has been signed.
The bot used is `MetaMask/cla-signature-bot`, which is a fork of
`Roblox/cla-signature-bot`. The fork has a couple of improvements, and
it updated the PR comment text to be more appropriate for our usage.
Currently the only user on the `allowlist` is `dependabot`, but any public
members of the MetaMask organization will also be exempt from needing
to sign the CLA due to the `allow-organization-members` setting.
The signatures are stored in `cla.json` on the `cla-signatures` branch,
which is in this repository as a distinct root. We can consider moving
this to a separate repository in the future - this was just easier to
setup.
