Allow more forms of specifiers in the config for import-name

[JoshuaKGoldberg]

Continuing discussion from #387 and #429: we should allow both "graphql-tag" and "graphqlTag" in the config for import-name.

At the very least, adding _ should be done here.

Hi @JoshuaKGoldberg , I am a novice to typescript and would like to contribute to this issue for hacktoberfest

[JoshuaKGoldberg]

Awesome, please do!

As per discussion #429, it should also provide ability to support entire path as replacementKey.

Proposed in #429

import _ from 'lodash'
import _ from 'lodash/fp'
import ReactDOMServer from 'react-dom/server'

"import-name": [true, {
  "lodash": "_",
  "lodash/fp": "_",
  "react-dom/server": "ReactDOMServer"
}]

---

So as per my understanding, this change should allow replacement-key to be entered in three ways:

Example:

import ReactDOMServerTag from 'react-dom/server-tag' 

Possible ways to provide exception for import-name rule:

"import-name": [true, { "react-dom/server-tag": "ReactDOMServerTag"}]

or

"import-name": [true, { "server-tag": "ReactDOMServerTag"}]

or

"import-name": [true, { "serverTag": "ReactDOMServerTag"}]

@JoshuaKGoldberg is my understanding correct ?

@JoshuaKGoldberg I have raised basic PR-522 to address this issue and is open for review.
