Fix handling of pre-releases in frameworkVersion validation

[medikoo]

Some of our tests (https://github.com/serverless/serverless/pull/8163/checks?check_run_id=1057358350) in v2 pre-release branch got broken when frameworkVersion was unconditionally added to serverless configurations.

It's due to pre-releases not being matched by * version range (reason unknown -> npm/node-semver#329)

This patch ensures, that * matches pre-releases as well.

Additionally provided workaround for EFS integration test CI fail: https://github.com/serverless/serverless/runs/1056731807
