fix: inaccessible env settings on un-published projects

[AdityaHegde]

We show a link to settings page while editing .env on cloud. This wont be available when there is no prod deployment yet. So removing the link when the project is unpublished.

Checklist:

• Covered by tests
• Ran it and it works as intended
• Reviewed the diff before requesting a review
• Checked for unhandled edge cases
• Linked the issues it closes
• Checked if the docs need to be updated. If so, create a separate Linear DOCS issue
• Intend to cherry-pick into the release branch
• I'm proud of this work!
