Error if version not in MAJOR.MINOR.PATCH format

[juanrgon]

Problem

Was running into this error when trying to install go 1.25:

> asdf install golang 1.25
Invalid version format: '1.25'. Go versions must be in the format 'major.minor.patch' (e.g., '1.25.0').

Took me a while to realize that the issue is that the version has to be in MAJOR.MINOR.PATCH format, e.g.

this

asdf install golang 1.25

not this

asdf install golang 1.25.0

Fix

This pull request introduces a new utility function to validate version strings in the lib/helpers.sh script. The main change is the addition of a function that ensures version numbers conform to the expected major.minor.patch format.

Note

Add version format validator (MAJOR.MINOR.PATCH) and invoke it in the Go download path.

• Validation:
  • Add validate_version in lib/helpers.sh to enforce major.minor.patch (e.g., 1.25.0).
• Download flow:
  • Call validate_version in bin/download's download_golang before building the download URL.
