Small mistake in build instructions Note for packager

[lukeflo]

I encountered a small flaw in the docs regarding building Helix from source. But since my Rust/Cargo knowledge is very limited, I'm not sure if it is a real bug, just a copy/paste typo, or my misunderstanding. Thus, no big bug report here, but a simple issue.

In the section Note to packagers under point to of the numbered list it is stated that the command cargo build --profile opt --locked --path helix-term should be executed to build Helix from source.

But if you run the command (after exporting the needed HELIX env variables, of course), yo'll get the following error:

cargo build --profile opt --locked --path helix-term
error: unexpected argument '--path' found

Usage: cargo build --profile <PROFILE-NAME> --locked

For more information, try '--help'.

Also the manpage, invoked with cargo help build, does not list --path as valid argument for the build command.

It might be a copy and paste error since in the initial section the command cargo install --path helix-term --locked is proposed for building Helix from source.

At least, AFAIK, building Helix with cargo build --profile opt --locked works just fine without the --path helix-term argument.

But as mentioned above, there might be another reason for the --path argument with the build command, I'm not aware of.

Yep good catch, I believe that's just a copy/paste bug. Feel free to submit a PR. That document lives here: https://github.com/helix-editor/helix/blob/master/book/src/building-from-source.md

Is that really worth a PR? Someone with write permissions only needs to delete the words --path helix-term from the line cargo build --profile opt --locked --path helix-term.

But if you prefer the PR way, I'll do it when I find some time.
