Add created branch (from dvc exp branch) to the experiments table

• If a user creates a new branch using the extension, we add the newly created branch (if it exists) to the table

I'm not sold on the utility of this. A few months ago we started moving away from auto-magical behaviour as it unnecessarily complicates the code and leads to unexpected behaviour for users.

Good job!

I'm not expecting what I will say next to be added to this PR. It could be a follow-up for later on if we agree on it.
I feel like there is a good amount of time passing between when we create the branch, when we show the toast and when we add the branch.
It is a lot more advanced, but having some sort of loading at the bottom of the table from the time the user creates the branch to when we add the branch would feel less confusing for the user. Some message that says "branch-name is being added to the table."

@sroy3 , with the latest change (only needing to run an update once), the table runs a lot faster. Plus, my computer tends to run on the slower side. If you have a chance, could you test this feature out with the newest changes? If it feels slow, I can work on adding a Toast message that says something like Adding branch to table... at the very least.

It does work almost instantly. Great work!
