Missing docs for comment-spacings rule

[BryceBeagle]

Describe the bug
A clear and concise description of what the bug is.

revive outputs links to docs for each rule. There are missing docs for the comment-spacings rule

The link in

│    (121, 3)  https://revive.run/r#comment-spacings  no space between comment delimiter and comment text     │

takes the user to a non-existent section on the docs page.

To Reproduce

• Introduce comment-spacings lint violation
• Use an output format that includes links to the docs for the violated rule
• Click embedded link to docs

Expected behavior
Docs should be present for this rule

Additional context

This rule is pretty self-explanatory, but it would be nice to have docs for it for the sake of completion.
