No support for "tel:xxxx", "mailto:xxx" like urls

[daKmoR]

I run all < href="x"> url through normalize... but it does fail on standard protocols like mailto:, tel: .

should that be supported or do I need to "filter" non-http-like URLs before?

Code to reproduce

import normalizeUrl from 'normalize-url';

// 1.
console.log(normalizeUrl('tel:004346382763'));

// 2.
console.log(normalizeUrl('mailto:office@foo.com'));

Expected behavior

Do not touch the URLs e.g. return tel:004346382763 and mailto:office@foo.com

Actual behavior

1. it throws

TypeError [ERR_INVALID_URL]: Invalid URL
    at new NodeError (node:internal/errors:387:5)
    at URL.onParseError (node:internal/url:564:9)
    at new URL (node:internal/url:644:5)

  input: 'http:tel:004346382763',
  code: 'ERR_INVALID_URL'
}

2. Results in http://foo.com

Investigation

it always seems to prepend http: which leads to the invalid http:tel:004346382763 URL which then throws on the new URL here https://github.com/sindresorhus/normalize-url/blob/main/index.js#L96
