feat: update Go version and dependencies (#111)

* feat: update Go version and dependencies

Updated Go version requirement to 1.22 in `README.md` and `go.mod`. Also added missing indirect dependencies and updated Ethereum dependency version in `go.mod`.

* fix: update Go version in CI workflow to 1.22

* feat: modernize tests and update metadata

Reordered imports in test files and replaced ioutil.ReadAll with io.ReadAll for compatibility with modern Go standards. Improved error handling in defer statements for better clarity. Updated copyright year in LICENSE and cleaned up an obsolete build tag in secp256k1_cgo.go.
