Hi,

I'm not sure how this works for others, but for me the Octokit createAuth call fails with Invalid character error.
https://github.com/github-aws-runners/terraform-aws-github-runner/blame/a8158d4961832afb42085ef7b6075d889c198ac3/lambdas/functions/control-plane/src/github/auth.ts#L94

I think it's in the previous lines the key is decoded from base64 while the function is expecting base64 pem encoding.

Could someone with more JS knowledge have a look at it?
