<issue_title>Unused import in docs/source/conf.py</issue_title>
<issue_description>This issue is a re-attempt at #3138 but with extra Copilot prompt regarding commit messages.

Problem Statement

Simply remove the unused import statement import sys from line 4 of docs/source/conf.py. This does not affect the existing functionality, as the module is not referenced elsewhere in the provided snippet. No other imports or code need to be altered. The only change is to delete or comment out the line containing import sys.

Copilot Instructions for ScyllaDB Operator

• "Document automatic data cleanups"
• "Add IPv6 support for ScyllaClusters"
• "Reword platforms to environments"
• "Update maintainers in the Helm charts"

Prefer commit message length under 72 characters.

The commit message should never include "@mentions" or hashtag ("#") references. The commit message should never include keywords that close issues.

Do not create a separate commit for the initial plan. Create only one commit in all circumstances.

The PR title should follow the same rules as the commit message.</issue_description>

Hi @Copilot. Thanks for your PR.

I'm waiting for a scylladb 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.
