Add e2e test for file signing

[elsesiy]

Generates a test file from the GHA workflow that gets signed in the e2e test similar to image signing

What type of PR is this?

/kind cleanup

Which issue(s) this PR fixes:

Fix #93

Special notes for your reviewer:

Since the test suite uses keyless signing, I haven't fully tested the patch using the existing workflow. There's a few options that I can think of:

• Run e2e also on PRs (preferred)
• Mirror the repo to duplicate the workflow and testing setup

Does this PR introduce a user-facing change?

NONE

Hi @elsesiy. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

You're welcome! Are you ok with me updating the workflow to run e2e on PRs as well or should I create a separate demo repo to test?
