Use case for Linux distro choice in install.sh

[mentalisttraceur]

Just a small stylistic cleanup. I was looking inside install.sh and spotted this if which can be less noisy as a case.

[formatting notes]

I imitated the formatting used in the other two case statements in this file as much as reasonable (the only thing I did differently was add a line break between the patterns and their commands, since that on-the-same-line condensed form stops making sense when the case patterns and/or the commands are too long), but I recommend having case patterns on the same intendation level as the case keyword/block. I don't think it adds any clarity or readability to have two indent levels for every case when a single one contains the same information unambiguously.

I also kept the quoting the same, but in shell I recommend the habit/practice of using ' instead of " whenever you don't need the special interpretation/expansion that " has.

The file seems to mix tab-for-indent and two-spaces-for-indent. I used tab for the lines I touched because that seems to be the intended (far more common) one, but I left the other lines alone to keep the PR diff clean/focused.

I don't know why 5/6 of the PR's automated workflows are in "Expected - Waiting for status ..." state. Anyone have any ideas? Should I just push a dummy empty commit to force it to re-run or something?

Thank you! That's much neater.

The CI wasn't running as I need to approve it

I'll merge regardless of the failure, as it's unrelated to this diff. I suspect a rebase would resolve it.
