Calendar: Time input doesn't allow PM when typed in

[jgalb]

Describe the bug

Using the Calendar component with the time-only flag and 12-hour format, when typing in a time like 10:35 pm, the time always reverts to 10:35 am.

I have pinpointed the bug to a specific line in the Calendar component code.
https://github.com/primefaces/primevue/blob/master/src/components/calendar/Calendar.vue#L1786 which reads:

this.pm = ampm === this.$primevue.config.locale.am || ampm === this.$primevue.config.locale.am.toLowerCase();

You can see that it is checking whether or not you typed pm by comparing it against am values. So typing pm will never work.

Steps to reproduce the behavior

1. Type a time into a time-only, 12 hour duration Calendar that has a pm at the end. e.g. "04:30 pm"
2. notice the time picker will change values, but the "am" will stay the same.

Expected behavior

You should be able to type in am or pm into the time input and have it be reflected in the time picker widget.
