fix: use proper format for congo phone numbers

[jeffscaturro-aka]

Description

What an awesome package you've put together! I started using this in a project, and came across an incorrect formatting for phone numbers in the Republic of Congo.

Motivation and Context

In order to provide the correct format for a phone input for the Republic of Congo, I had to update the mask in lib/formatters/phone_input_formatter.dart. The proper mask should be +000 00 00 00000. Reference

Changes Made

Updated the mask to use the proper format.

How to Test

You can use the international code +242 to start formatting a Congo number.

Checklist

• I have followed the project's coding style guidelines.
• I have performed a self-review of my code.
• I have written unit tests or provided a rationale for why tests are not necessary.
• I have updated the project documentation if necessary.
• I have added necessary comments and documentation within the code.
• I have tested my changes locally and they work as expected.

Additional Notes

You currently have two failing tests around the formatting of numbers in the Philippines. I didn't want to touch those in this PR though due to separation of concerns, but wanted to mention it.

Let me know if you need anything else changed, like the version or something.

Thank you again, @caseyryan!

Also, for what it's worth, I understand we can use replacePhoneMask but it'd also be nice to get this corrected so we don't have to replace it and DRY up some code. :)

Hi! Impressive work :) Just changing the mask would be enough but you've made a test for it and and the great description. Thank you! I'll merge it as soon as possible

There is PhoneInputFormatter.addAlternativePhoneMasks() with "mergeWithExisting" parameter. Doesn't it do?

Your fix is now in 2.11.1
