v2.0.0

This update provide the following (should be no breaking changes):

• Update to Node 20 (thanks @marians)
• Adds test-pkgs option to explicitly specify packages to test (thanks @khasanovbi)
• Adds notes-ref option to set an explicit reference to use for git notes instead of the default of gocoverage (thanks @raleksandar)
• Adds coverage outputs rounded to 1 or 2 decimal places which makes it easier to produce better formatted badges, etc - See coverage-pct-0dp, coverage-pct-1dp, coverage-last-pct-0dp, coverage-last-pct-1dp
