[readme] fnm -> nvm.fish

[kidonng]

fnm has been renamed to nvm.fish and the repo has been transferred to https://github.com/jorgebucaran.

That’s unfortunate; i thought @jorgebucaran and i went through this with the name not being “nvm” years ago.

[jorgebucaran]

Yes, I renamed it to fnm, but when that other fnm came into the picture a few years ago, I went back to nvm, adding .fish to the name, so its actual name is nvm.fish. Not nvm. The README also states in its first sentence that we're not affiliated to this project.

Not that POSIX-compatible script.

[ljharb]

So rather than ask the new fnm to rename to avoid the conflict, you decided to create a new conflict?

[jorgebucaran]

In my view, there is no conflict. nvm is an sh script. nvm.fish is a Fish one.

There's also a thread on Twitter with more background if anyone is interested. Also Schniz/fnm#3.

[kidonng]

Yep, I stand with @jorgebucaran here. It may be the case years ago, but I don't think nowadays anyone consider nvm to refer to something else than this project.

[ljharb]

This confusion empirically continues; people think nvm-windows is nvm constantly, and the only reason I don't see it for nvm.fish is likely because fish itself is so rarely used. However, obviously the readme should point to the correct project, so I'll rebase and pull this in.
