Change "Cargo Doc" section to "Rustdoc" on tools page

[camelid]

What needs to be fixed?

Currently on the tools page, it says:

"Cargo Doc" seems a bit out of place given that another section is shown as "Rustfmt", when usually you use it as cargo fmt.

Page(s) Affected

/tools

Suggested Improvement

Change "Cargo Doc" to "Rustdoc"

Side Note

Also add cargo fmt to this list on /learn/getting-started?

I'm not sure I agree, the name rustdoc is not as popular in the rust community since people never directly invoke it, whereas people are kinda used to the names rustfmt and clippy.

[camelid]

But this page is mostly for new contributors who won't necessarily know the names clippy and rustfmt anyway, right? That's why it explains what they do. And calling it Rustdoc will probably get more people more familiar with it.

@camelid Yes, but the point is that you want to teach people the terms other people will use, so that they do not have to learn a second thing.
