Occasional sv2_template_provider_tests timeouts

[Sjors]

So far I've only seen it in https://github.com/Sjors/sv2-tp/pull/10:

• https://github.com/Sjors/sv2-tp/actions/runs/17395389917/job/49376250892?pr=10
• https://github.com/Sjors/sv2-tp/actions/runs/17395389917/job/49376250881?pr=10

It happened after I rebased on #12 (cc @Eunovo), but this may be a coincidence. This test has been flaky in the past.

I opened #14 to determine if this has anything to do with #10.

Another one:

Hopefully #12 fixed this, closing for now.
