chore: Updating iOS and Android package versions

[izaaz]

Updating the underlying android and iOS package versions to use the latest available versions.

• The asm files were added back because removing them breaks the ability to add the unity plugin using the package manager.
• We generate 4 different unity packages
  • amplitude-unity.unitypackage
  • amplitude-unity-all.unitypackage
  • amplitude-no-edm.unitypackage
  • amplitude-unity-no-edm-and-dep.unitypackage

They used to be generated and stored in different branches but I am starting to commit them in main branch instead. This does not break the Package Manager based import route.

I've also stopped producing amplitude-no-edm.unitypackage because the contents of this are exactly the same as amplitude-unity.unitypackage. So will only generate that again if there's a need for it.

There have been some requests for amplitude-no-edm.unitypackage. https://github.com/amplitude/unity-plugin/issues/111

Ah they also want a separate tag. Will update that branch too then.
