Update goals to reference lang-docs

[traviscross]

In the context of a project goal reserving the bandwidth of a team, the work of reviewing and revising proposed Reference text at this time falls more on the T-lang-docs side rather than on the T-spec side. So let's update the relevant project goals and the template accordingly.

Sounds good, thanks!

@traviscross the CI failure comes from the fact that the team asks have specific wording defined here:

rust-project-goals/rust-project-goals.toml

Line 20 in 809a3f4

"Finalize specification text" = { short="Spec text", about="assign a spec team liaison to finalize edits to Rust reference/specification" }

If this is more accurate I'm happy to update that file, but I think we should have someone from @rust-lang/lang-docs chime in as well.

Thanks. Fixed.

I'm on lang-docs and one of the currently N=2 people who merge Reference PRs. This change is OK and improves clarity given how things work today.

Ah right, it's just you and Eric isn't it? Looks good, thanks!
