[package_info_plus] Added supported platforms to README.md

[nilsreichardt]

Description

When I read the README.md of package_info_plus it wasn't for me clear, which platforms are supported. You can see it maybe with the dependencies like package_info_plus_linux. However, it is very hidden. And in the description of the pubspec.yaml, which will be displayed at the right side, mentioning only Android & iOS which is confusing (My thoughts: Why not also mention Linux, Web, macOS and Windows? Or is there no support for this platforms)?

Should I also add the other packages to this PR or should I split it in many small PRs (like this PR)?

@nilsreichardt I don't mind either way, however works best for you!

Also @pr-Mais was planning to do this, you should coordinate so you are not doing the work twice.

@nilsreichardt thanks for the PR, I was just thinking of doing one, you can add the supported platforms for all of them, I will be working on adding more examples, so we won't conflict each others.

@pr-Mais I you want you take over. I did this for package_info_plus so I cloud create a screenshot for #111.

[pr-Mais]
