Replace context.Background() → t.Context()

To quiet down "usetesting" linter.

I guess this is an argument to switch to Go 1.24: the t.Context() doesn't exist in Go 1.23, but using context.Background() in the test with 1.24 throws a linter error.

The linter says that it will disable itself if you run it with an older version?

https://golangci-lint.run/usage/linters/#usetesting

So I guess the entire sub-linter should be removed, until the go version is bumped

i.e. context-background: false

Makes sense to me; we just need to remember to enable it again when we bump the Go version...

I think there were three of them (for go1.24), but not sure if we ran into the others

Templating the linter config sounds like overkill to me, maybe a reminder comment?
