[ci] `check-license` should not look at lockfiles.

[ditman]

The check-license workflow just failed because a pnpm lockfile was missing a license.

Lockfiles are tool-generated (and meant to be regenerated), so it's very likely that this file (or a similar one) will end up failing the check again.

Configure the check-license workflow so it doesn't look at lockfiles.

(@selamw1 I don't know why the automation assigned this to you, feel free to un-assign yourself if you're not going to work on this)

Thanks @ditman. Yes, new issues are automatically assigned to me first via GitHub Actions.

I've opened PR #1142 to ignore lockfiles in the check-license workflow.

Thanks @selamw1! @zeroasterisk explained what's up!
