fix: lint 💚

[robertoschiavone]

Description

This commit bumps go version to 1.21.0 and changes go get to go install.

Motivation and Context

Current workflow for PRs is broken because the tool that is invoked to format the code, shfmt, requires go >= 1.19.

How Has This Been Tested?

Workflow was launched again after fix and it doesn't fail anymore.

Types of changes

• Bug fix (non-breaking change which fixes an issue)

It looks like #2224 that I just made is similar - but I have also updated the GitHub actions that we use

[davidpfarrell]

For KISS reasons I think we should go with this one, but thank you all for taking the time to get this fixed !

Sounds good - perhaps I should update mine to only make only the Actions upgrades once this is merged

Yeah we can do that ... One Q on it (which I should have posted over there on it): Are the quotes needed? Although technically more correct, having some quoted and some non-quoted values feels less clean than current .... I would say leave unquoted unless needed

[hyperupcall]

Yeah quotes in YAML aren't needed unless they're actually needed. I've heard too many near-death experiences from YAML that I have a habit of quoting everything I touch. But no worries I'll make the changes without quotes this time around (unless you want everything to be quoted, which seems unlikely)
