ci: update installed version of VTune
This updates the installed version of VTune to v2025.7.0. See https://github.com/abrown/install-vtune-action/pull/7.
Well, that's twice in a row runners ran out of space. However it was on jobs this change doesn't even affect. So here's hoping it was spurious...
And if it was spurious, well, that's also worrisome!
Ok now THAT looks like a legitimate failure
Ok, well, the one thing I changed is to use v3 instead of v2 for the install-vtune action. That shouldn't have really any effect (it's just an older version) but, hey, maybe that older version has some problem. I did also check this out locally with v2025.7 and everything works there. I'll re-add this to the queue.
