Add miss and tenn seals

[quevon24]

I added miss and tenn seals.

For the moment I added the mississippi judiciary seal while I wait for the response (I sent an email to the court asking for the seal) from the other seal I found:

I think this isnt quite right. The seal here is used by the workers comp boards but isnt the seal of the tenn. Supreme Court. think you need to add the workers comp courts to the list and link that Agriculture seal to them - not add it to the Supreme Court here

I already corrected the seals and, taking advantage of this, i added the correct one for Tennessee Supreme Court

@flooie I think pre-commit.ci was configured for this repo but we never added the .pre-commit-config.yaml file, i added it and now precommit check works correctly

I also updated the checkout and setup-python actions in the workflow files

Right now I'm finding out why it modifies several svgs, I think it's because of the precommit

Update: Some svg and other files were updated because missing new line at the end of file (https://stackoverflow.com/questions/729692/why-should-text-files-end-with-a-newline)
