Update runners to ubuntu-24.04 from deprecated ubuntu-20.04 label (#2761)

This is a LSC run by http://go/ghss to upgrade all depreacated
ubuntu-20.04 runners to ubuntu-24.04.

On April 1, 2025, GitHub will stop supporting ubuntu-20.04 runners and
workflows configured with this label will cease to run. This PR is an
attempt to save you work by doing the upgrade for you.

WARNING: We do not know if the updated label is compatiable with your
workflow or not.

If you do not want to merge this PR, feel free to close it and deal with
the problem yourselves.
