ci: skip artifact creation for upstream testing for forks

[zimeg]

Summary

This PR skips artifact creation and E2E tests for PRs created from forked branches. Workaround for edges of git in CI.

Notes

• The "build-lint-test-e2e-test" workflow is required and can be started for forked PRs with these steps 📚
• The "build-lint-test-e2e-test" workflow includes a step with goreleaser that is kept as a build test 👾

Requirements

• I've read and understood the Contributing Guidelines and have done my best effort to follow them.
• I've read and agree to the Code of Conduct.

@mwbrooks Thanks once more for the review on this testing saga 🤖

I'm closing this PR since we're finding that branches from a fork can still be tested with the right set of permissions. Or moreso skipped changes to the .github/workflows files.
