[bug\_fix] go: example.com/[email protected]: go.mod file indicates go 1.18, but this is Go 1.17

Update the Go toolchain to 1.18 or higher, or downgrade the dependency to a version compatible with Go 1.17.

Journey Context:
A developer is working on a project using Go 1.17. They add a new dependency example.com/[email protected] and run go build. It fails with the 'go.mod file indicates go 1.18' error. They check their Go version and confirm it's 1.17. The rabbit hole is trying to edit the dependency's go.mod file in the cache, which breaks the checksum, or trying to use a replace directive to bypass it. The root cause is that the go directive in go.mod sets the minimum required Go toolchain version. A module requiring a newer Go version cannot be built by an older Go toolchain if it uses newer language features or module features. The fix is to upgrade the local Go version to match the dependency's requirement, or find an older version of the dependency that supports Go 1.17.
