Implement N-1 support policy for Go versions

[yurishkuro]

Follow up to #4329.

• implement a linter check scripts/check-go-version.sh that verifies that all our build scripts are using the same Go version N, but go.mod is N-1. This includes GH actions, Alpine images, etc.
• implement a convenience script scripts/update-go-version.sh that updates those scripts to another version, to make these upgrades easier in the future (see Add shell script to ensure consistent version of OTEL semconv #4652 for reference). It should also bump go.mod to N-1.
• add a section to README (similar to Version Compatibility Guarantees) explaining the policy. For reference: https://github.com/open-telemetry/opentelemetry-collector#compatibility

Since Go 1.21 is out, this is an opportunity to test this new process.

Hi @yurishkuro ,

in task 1 : "verifies that all our build scripts are using the same Go version N"

1.how do i find those build scripts from such large code base ?
2.Are these {build scripts} present in "script" folder as ".sh" files?

hey @yurishkuro what is the estimated/expected time limit if any for these issues to get resolved/implemented?

Hey @yurishkuro as I was trying to setup the project I encountered this issue

I have already tried removing the go.sum and then regenerated it using go mod tidy but still if gave me the same error. I am new to contributing and stuff, can you suggest me what should I do next ?

Continuing this, I faced issue in running make lint because github.com/golangci/golangci-lint/cmd/[email protected] was not able to install correctly. When I installed its updated version go install github.com/golangci/golangci-lint/cmd/[email protected] everything seems to work fine now. Should the version be changed to 1.54.1 ?

Should the version be changed to 1.54.1 ?

If we upgrade golangci-lint, we'll be subject to the problem described in: golangci/golangci-lint#3906, where a large number of depguard lint errors appear.

We'll need to understand why those linting errors are appearing and what actions need to be taken to address them, or if it's better to stick with the current version until that problem is ironed out in a later version.

FWIW, I didn't have any issues installing 1.52.1.
