An unfortunate bug caused a number of packages in old x/tools versions
to fail to build with Go 1.25 (https://go.dev/issue/74462). Fix this
minimally by updating to the lowest patched version with the fix:
v0.24.1. This should allow wire to continue building with the same range
of Go versions as it could build with before (down to 1.19).
Also:
- Update the go.mod go directive to Go 1.19 to allow for module graph
pruning, and to be consistent with the minimum build version.
- Fix a test that is broken in recent Go versions due to an error
message change.
- Update tests to run on Go 1.25.x (the most recent version of Go).
- Remove coverage, since coverage upload wasn't working anyway.
