github-ci: fix authors check with special characters

Dependabot is always getting flagged as a new author even tho it uses
a consistent author of:

dependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com>

But this doesn't work with plain grep. Fix by telling grep to treat
the value as a fixed string instead of a regular expression.
