GHA: Add additional checks for common issues (#1922)

* GHA, tests: Add additional checks for common issues

These checks include:
- Ensuring that all testify funcs use their formatted variants (e.g., `assert.Equalf(t, expected, actual)` instead of `assert.Equal(t, expected, actual)`).
- Replacing `%s` with %q
- Enforcing consistent usage of should/must wording for testify assert/require messages

* Add support for checking backticked string format specifiers and fix issues

* tests: Fix error comparisons

* tests: Replace errors.Is(err, nil) usage with testify and automate check

* refactor: Rename ExtractPort to ExtractPortOrDefault

* tests: Replace assert with require for error handling in multiple test files

* tests: Replace assert with require for error handling and improve assertions in data tests

* tests: Fix typo in assertion message for StreamVol test

* OKX: Fix GetOpenInterestAndVolumeStrike test with instrument selection and improved assertions

* OKX: Revert intentional error check

* Improve error message for expiry time check in GetOpenInterestAndVolumeStrike test
