Update cargo-fetch.md to remove cargo-prefetch reference

Remove the mention of the cargo-prefetch plugin, as it appears to be unmaintained.

I suppose this would be fine. There never seemed to be much interest in this subcommand. However, can you say what the issue with it may be? AFAIK, it should still be working. And why this is opened as a draft?

I don’t have a strong opinion, I opened this PR mainly to gather feedback. If we decide we want to keep this information, it probably belongs in the See also section rather than the Description section.

kinda agreed with this. No strong opinion on removal or not

I think the bar should be high to recommend external plugins in the documentation for built-in Cargo commands. Given the low usage shown by the statistics on crates.io, I think this reference should be removed.

I was curious about the intent for the See also section. The only reference I found is from https://www.man7.org/linux/man-pages/man7/man-pages.7.html

A comma-separated list of related man pages, possibly followed by other related pages or documents.

It sounds like the intent is purely for cross-referencing but I feel that isn't as appropriate here because we would want to provide the context for why.

Some times the Cargo team needs to experiment and advertise the experiment to see what would be useful, so going purely off of download counts won't always be applicable.

In this case, this has been a while and ehuss mentioned it hasn't had much use. I can go either way.
