add mise install path for apt installations

[jtannas]

Motivation

Closes #3531 (LSP fails to detect mise that is installed via apt into /usr/bin/mise)

Implementation

Followed pattern laid out in #2943 for multiple install locations.

Automated Tests

No tests added since #2943 has none that I could use as a starting point to follow.

Manual Tests

Follow the reproduction steps in #3531 to see if the problem has been resolved.

Thanks for the PR! The code looks good, but there are some styling issues. You can automatically fix those by running yarn run format inside the vscode directory.
