Account Creation: International phone numbers deemed invalid due to length

[MarioLiebisch]

Describe the bug I tried to setup a cloud account to test the service, but had to lie/fake the phone number field, as our actual German business phone number didn't pass the validity test, as it's deemed to be too long (which it isn't. according to standards).

To Reproduce Steps to reproduce the behavior:

1. Start creating an account
2. Try entering a longer German telephone number in international notation: +4911112222222 (1s = area code, 2s = local number)
3. Move to he next input field and observe the number being deemed invalid

Expected behavior The phone number should be accepted, even if it's longer than a typical US number, as long as it satisfies ITU-T E.164.

Screenshots

Additional context OneUptime currently follows ITU-T E.123, which uses the US 3-3-4 format. This won't work for some international numbers, like many German ones, as the area code might consist of up to 4 digits (ITU-T E.164 allows up to 15 digits total, compared to E.123's 12 digits)
