chore: use os.MkdirTemp instead of ioutil.TempDir

[atombrella]

📑 Description

• Replaced deprecated library function in a test util file.
• Added make quality to the build CI pipeline to guard against future lint failures

I have added a .golangci configuration file, but silenced a few matches from gocritic. One of them is hugeParam which yields a few matches. Maybe it's worth looking into. exitAfterDefer has a single match, but in the starter-function for the tests.

I'm a bit fed up with spam caused by leaving my email address in git commits, hence the anonymous address.

ℹ Additional Information

I opened various files in VSCode and hit save. It does "golang import-style" as well as go-formatting when doing so.

Hey @atombrella - it's been a while! 👋

Nope, all good, I just didn't see this PR - ✅

@owenrumney I don't have merge rights :) I see that there's something odd with go.mod. There are also two PRs from dependabot.

Cheers :)
