Remove CI/CD variable validations on AWS keys
Previously AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY had a strict, 40-character regex based on Amazon's recommendations. However, many S3-compatible providers use values that don't adhere to this regex.
To make these CI/CD variables work with other S3 providers, eliminate the validation altogether.
Closes #215557 (closed)
