Resolves #1497

As per @pascalberger's suggestion, I reached out to the creator of the Cake.ArgumentHelpers to see what his thoughts are in reviving his addin and possibly merging Cake.Args into it, instead of having two separate addins with very similar goals.

I'll wait a few days to see if I get a response. Marking as blocked for now.

Got an initial response from Adam and he'll let me know if he can find some time to do the following:

As soon as possible

• Update Cake reference libraries v0.33.0
• Multi-target net461 and netstandard2.0
• Update the categories of the aliases (PR from @pascalberger)
• Merge the method ArgumentOrDefault from Cake.Args into Cake.ArgumentHelpers
• Release Cake.ArgumentHelpers v0.4.0 to nuget.org

After we release Cake v1.0.0

• Update Cake reference libraries to v1.0.0
• Include net5.0 target (and keep net461, netstandard2.0)
• Release Cake.ArgumentHelpers v0.5.0 to nuget.org

ps: Did I forget anything?
