Incorrect time separator for ms and ms-my locales

**Describe the bug**
The time separator in ms and ms-my locales is `.` instead of being `:`.

**Expected behavior**
12:34 pm instead of 12.34pm

**Information**
- Day.js Version [v1.11.20]
- OS: [MacOS]
- Browser [Chrome 147]
- Time zone: [EST]

Locate the locale definitions and time-formatting path for the ms and ms-my locales. Reproduce the reported output and compare it with the expected `12:34 pm` format. Done means both locales use a colon as the time separator, with tests covering the corrected behavior.
