[Archive] Repositories settings changes and standardization throughout the Organization

[kbdharun]

Documenting the changes I made yesterday and today.

Prologue

Throughout this issue, I used square brackets [] to represent the change's scope wherever possible.

Changes

• I have enabled the option to use the PRs title as the default commit message for the merge commit as suggested by @sebastiaanspeck in the chatroom earlier today. [All repos]
• I have enabled the delete the head branch by default when the PR is merged [A few repos in which it wasn't enabled] (Note: The branch is still easily recoverable even after deletion)
• I have enabled the option to suggest updating the PRs branch when there are changes in the default branch(This is to avoid issues in the main repo where contributors build on top of their existing branch and oftentimes existing pages/commits by different people are displayed as new additions/modifications. [All repos]
• I disabled merge using a merge commit option in tlrc as we follow the same across our repos and suggest Squash & merge or Rebase & merge PRs as the default workflow.
• I enabled Private Vulnerability reporting, Dependabot version updates and Secret Scanning Alerts in Security Settings for tlrc as we follow it throughout the Org.

Edit.

Additionally, I have enabled the Push protection (on the Org) when a supported secret is detected i.e. deploy keys, etc. Although it is highly unlikely that someone might commit a secret, IG it's better to be cautious.
