Ability to filter PR commits by commit-hash range

[fluffynuts]

On pull requests which are undergoing review, where the requestor has been attending to requested changes, it's really useful at GitHub.com to be able to filter by commit -- that is, to be able to view a ranged subset of commits for a PR so that only the latest changes can be observed to decide on approval for a PR which has undergone review and subsequent work.

At the moment, this would even be good enough through a command-palette interaction, for example, running the command "GitHub Pull Requests: Filter Current Request" and then getting a list of the commits, by hash (with the beginning of the commit message) in a list where one could ctrl-click or shift-click to select ranges of commits of interest, or just click to select a single commit of interest.

Proposing to reopen this one.

In our case we have a merge squash approach with linear commit history. This means that we sometimes need to merge main back into the PR. This will cause 1 or more commits to be part of the "since last reviewed" part, but as they came from main they were already reviewed.

On GitHub there is a way to review only a subset of commits in a PR.

The blue is the selected commits and using the "Show changes since your last review" will select all commits after your last review. Using the "hold shift + click to select a range" feature you can select any arbitrary subset.

It would be amazing to exclude certain commits from the review. I am thinking maybe there could be a button or highlight in the "> commits" section to indicate which commits are shown and exclude certain commits through a button, right click context, etc?
