Revert "ref(metrics): Add metrics for script run times (#72223)"

[joshuarli]

This reverts commit 09cdabf95781c69013f4dfddf4d1ef5d55f15b0e. Wasn't roll forwardable anyways since make instlal-py-dev goes through do.sh, which I plan on removing.

Functionality will be preserved as part of https://github.com/getsentry/devenv/pull/124 where span durations would work.
