docs: add hash to "tag" config link (#5519)

* docs: add hash to "tag" config link

Minor change.

[using-npm/config](https://docs.npmjs.com/cli/v8/using-npm/config) is a long page -- heck, the subtitle is "More than you probably want to know about npm configuration" -- so instead of dumping people at the top of it when they follow the link to learn about the "tag" config, let's send 'em right to the relevant bit.

Aside from it being a long page, one more motivation: trying to get to the section by searching is also slow, it's the 16th (of 24) occurrence of "tag" on the page. (though to be fair, only the 4th if they catch it in the table of contents)

* docs: fix some nonstandard formatting

* docs: more useful link
