Open Web IDE in a new tab from all contexts

Problem to solve

In most cases, when you want to make a change to a file in the Web IDE, you are navigating a project's repository or reviewing a Merge Request. In !102512 (merged), we introduced the behavior for the Open in button to trigger the Web IDE to open in a new tab. This behavior doesn't extend to the use of the keyboard shortcut . or for opening the Web IDE in the context of a repository.

Proposal

For consistency, open the Web IDE in a new tab when using the keyboard shortcut ..

Consider applying the same pattern to the repository views.

Questions

1. Are the use cases different enough when editing from the repository views to warrant opening in the same window?
