feat: Use version from Goreleaser

[yngvark]

Description

See GoReleaser ldlflags.

By default, GoReleaser will set the following 3 ldflags:
main.version: Current Git tag (the v prefix is stripped) or the name of the snapshot, if you're using the --snapshot flag
main.commit: Current git commit SHA
main.date: Date in the RFC3339 format

This in turn setsversion, commit and date variables:

ok/main.go

Line 11 in af8801f

version = "dev"

This can be tested locally:

go build -ldflags "-X main.version=1.0.0 -X main.commit=abc1234 -X main.date=$(date +%Y-%m-%dT%H:%M:%SZ)" -o ok .

./ok version

Version: 1.0.0
Date:    2024-07-17T12:07:21Z
Commit:  abc1234

Motivation

ok version should match the actual released version from Goreleaser.
