Simplify SDK consistency test to avoid flaky go list call (#4927)

## Summary

`TestConsistentDatabricksSdkVersion` started failing on CI
([example](https://github.com/databricks/cli/actions/runs/24219817586)).
The test used `go list -m -json` to resolve the SDK module version to a
git hash, then fetched the OpenAPI SHA from GitHub using that hash. The
`go list` command requires network access to the Go module proxy to
resolve VCS origin metadata, which was failing on CI.

This PR simplifies the test by using the version tag (e.g. `v0.126.0`)
directly in the GitHub raw content URL instead of first resolving it to
a commit hash. Since `raw.githubusercontent.com` accepts tag references,
the `go list` step is unnecessary.

## Test plan
- [x] CI passes
