Tel link doesn't work Link Plugin

[espipj]

Description

As of now tel: links doesn't work either but they're are included under default "allowedSchemas" here so sanitizeUrl will never run.

Related PR: #2444

Steps to Reproduce

Create a link in the editor using "tel:123456"

Expected Behavior

Link gets created if "tel" is under "allowedSchemas" (there by default)

Environment

• slate:
• slate-react:
• browser: chrome

It looks like the problem is that the default isUrl helper returns false for a correctly formatted tel: URL. If you could patch that helper to add tel: as a special case, that should resolve the issue, I think.

Changing isUrl to return true for anything that can be parsed with new URL(...) probably isn't what we want, since this would result in false positives when pasting strings containing colons. new URL('hello:world') // parses successfully
