mage: run mage update steps in parallel (#6871)

mauri870 · web-flow · commit 293092ca9b14 · 2025-02-17T13:59:10.000Z
From the looks of it, none of the update steps interact with each other, so
I don't see a reason to run them serially.

As an example, making a single line change in the otel components file results
in the following timings:

	parallel mage update  9.19s user 1.92s system 366% cpu 3.027 total
	serial mage update  20.20s user 2.93s system 181% cpu 12.748 total
