Add missing settings for Python 12 support

Thank you for your effort on this PR. However, I noticed a few confusing places:

• The title of this PR mentions bringing back versions 2.7, 3.6, and 3.7, yet the description references the addition of 3.12. Could you clarify this discrepancy?
• The initial PR Remove support for EOL Python 2 #40 seemed to take a reasonable step by discontinuing support for EOL releases. Could you explain the rationale behind reintroducing these versions in the current PR?

It would be beneficial for followers of this project if all PRs were a bit clearer in their intentions so that the community understand and support the project's direction more effectively.

It's in the second line of the PR/commit message.

As mentioned in the title, it's for 0.5.1 release.
We'll EOL Python 2 in the next major version (0.6.0)
