Adds description to elevation device tooltip

Fixes: #11801

Currently it looks something like this:

With a 200 char description, it looks like this (with devtools, so might be wrong):

I find it a little busy, it's hard to distinguish where the description starts/ends.

Maybe we could use some newlines and labels?

It helps legibility imo, but I'm not really a great UX'er :)

@kkthxbye-code I have implemented the way you have suggested.

I really like this, much cleaner! I went ahead and broke out the asset tag and serial to separate lines as well to improve readability.
