docs: add link on linter without configuration

[ldez]

This PR creates an invisible span with ID to generate an anchor for all linter names.

Result:

link example: http://localhost:8000/usage/linters/#bodyclose

This also fixes:

• "back to the top" link for linter without repo (ex: lll)
• the behavior of "back to the top" link when the repo icon is not on the same line as the linter name (ex: staticcheck)

Fixes #4841

"Top" button have underscore

Also, offtop, in contribution guideline need to fix .reference to next.reference

Maybe do it in this PR to not spam issues?

GitHub icon newlined somewhere

It's just related to the size of the cell, it's expected because it's a table and the icon is not a character, I cannot fix that.
FYI there is already a non-breakable space ( ) between the text and the icon.

"Top" button have underscore

It's not an underscore but a link decoration: the emoji is a character and not an image so the "text" of the link has a decoration.

Also, offtop, in contribution guideline need to fix .reference to next.reference

I updated the file name.

[ldez]

I replaced the emoji with an icon.

I just do not realize why we receive different column width in equal sections?

because it's 2 separated tables.

[Antonboom]

because it's 2 separated tables.

but why in the second one the description width is shorter? with equal rems

[ccoVeille]

That's why we do backend. Because we have no patience for such mess and nonsense.

I don't understand how frontend can work without becoming insane 😁

[ldez]

but why in the second one the description width is shorter? with equal rems

Because the sizes of the cells are computed based on the size of the cells of one table.
As there are 2 tables, there are 2 different computations.
The 2 tables don't have the same content, so the cell sizes are different.
