WIP: Remove parser, port C# Task, and other modernisation

[tboby]

WHAT

This combines #17 and https://github.com/MangelMaxime/KeepAChangelog/tree/feature/rework

It removes the parser library, replacing it with an F# port of #17's C# implementation.

It adds the tests from @MangelMaxime 's work, as well as porting the test from #17.

It makes the general build changes from @MangelMaxime 's work, including central package management, and package lock. These are slightly amended to fix a few issues/redundant bits.

This now works in Visual studio, for both C# and F# SDK projects, for both net472 and net6/8.

WHAT NOT

This doesn't (yet) have enough tests.

This doesn't actually make any improvements to the features of the task.

WHY

I wanted to work on an msbuild task, and @MangelMaxime suggested this one.

If this is reasonable as an approach, I'd like to start adding some of the low hanging fruit in issues.

[tboby]

Oh, and I know 17 mentions making it C# deliberately: I figure we can always swap back if the repo gets closer to a model example with all the other best practice changes made :)

Left a number of comments - this is all great work! The big question to me is what is the layout of the generated nupkg from this set of changes, and how does it compare to previous versions?

[tboby]

@baronfel I believe I've addressed all the current comments.

One outstanding question I have:
Is there any benefit to targeting net6.0 in the project if we require net8.0 msbuild?

[baronfel]

we should totally move to .NET 8 as part of this

[baronfel]

Enhancement that would make the diffs easier:

If you add <SatelliteResourceLanguages>en</SatelliteResourceLanguages> as a property to the Directory.Build.props all of those different language translations from FSharp.Core won't flow through to the packages.

[tboby]

I'll re-apply your deduplication of the build props/target files as well

This looks lovely - thank you for doing this. Do you have any final concerns? It all looks solid to me.

I think this is good as a first set: I'll look at improving the tests in the next PR!

Ironically, I didn't update the CHANGELOG.md
