No more working under npm 12

### Issue

Running `npx patch-package ...` under `npm 12` will now produce the following error:

```sh
npx patch-package nx
npm notice run npx
npm notice run 'patch-package' nx
patch-package 8.0.1
• Creating temporary folder

}

### Explanation

Changing `stdio` to `inherit` here:
https://github.com/ds300/patch-package/blob/be4dfd77d941c0e6fb56b60843f3a98fd1d7ba4c/src/makePatch.ts#L239-L246

will now gives better hint on the issue:

```sh
• Installing nx@22.7.5 with npm
npm warn using --force Recommended protections disabled.
npm error code EALLOWREMOTE
npm error Fetching packages of type "remote" have been disabled
npm error Refusing to fetch "nx@https://registry.npmjs.org/nx/-/nx-22.7.5.tgz"
npm error A complete log of this run can be found in: /Users/xyz/.npm/_logs/2026-08-02T00_31_48_537Z-debug-0.log
```

Npm 12 now set `allow-remote=none` by default, which blocks any background installations trying to download direct tarballs (.tgz files) from an absolute remote URL, even if it points to the official registry.

### Temporary solution

Use the following:
```sh
npm_config_allow_remote=all npx patch-package ...
```

### Fix

Add the argument `--allow-remote=all` to both npm commands:
