[BUG] npm version prerelease does not work with numeric --preid

[ntkme]

Currently --preid only works correctly with non-numeric value. I have actually root caused it down to a bug in npm/node-semver and submitted a PR to fix it: npm/node-semver#380. I'm opening this issue for tracking purpose and hopefully to get some attention from the npm team.

Current Behavior:

Case 1:

$ cat package.json
{
  "name": "test",
  "version": "1.0.0-2021.0"
}

$ npm version prerelease --preid 2021
npm ERR! Version not changed

Case 2:

$ cat package.json
{
  "name": "test",
  "version": "1.0.0-2021.1"
}

$ npm version prerelease --preid 2021
v1.0.0-2021.0

Expected Behavior:

Case 1:

$ cat package.json
{
  "name": "test",
  "version": "1.0.0-2021.0"
}

$ npm version prerelease --preid 2021
v1.0.0-2021.1

Case 2:

$ cat package.json
{
  "name": "test",
  "version": "1.0.0-2021.1"
}

$ npm version prerelease --preid 2021
v1.0.0-2021.2

Environment:

$ node --version
v16.0.0
$ npm --version
7.10.0

Actions:

• should support numeric --preids
• should error out more appropriately

[ntkme]

The semver spec says numeric should be supported:

<pre-release identifier> ::= <alphanumeric identifier>
                           | <numeric identifier>
