Fix broken link in README.md

[HebaruSan]

• Update README.md #413's text gave me some false hope that I could merge some .NET 10.0 assemblies until I checked the allowed values of /targetplatform again. Now ".NET assemblies" is replaced by ".NET Framework assemblies."
• The original link to ILMerge is now broken, so I updated it to the repo that works.

what issue did you see merging net10.0 assemblies? I don't know of reasons why it shouldn't work. Perhaps file an issue?

[HebaruSan]

Huh, it's somewhat encouraging that you expected it to work. The specific error I got was:

ERROR: Loading C:/path/to/file.exe failed: ILRepack does not support merging non-.NET libraries (e.g.: native libraries)

As far as I know, none of the DLLs or EXEs I'm merging are non-.NET libraries, and the equivalent build artifacts work just fine for net481, so I guessed that it was having trouble with versions of .NET post-Framework.

[HebaruSan]

Well, should I just close this, or do you want to keep the broken link fix?

[HebaruSan]

Confirmed as user error; I forgot that EXE files are no longer "assemblies" post-Framework.
When I try only repacking DLLs, it works fine, and I can even launch the resulting application.
