Parser displays weird behaviour on dates like "april2,2021"

[lucasabr]

Discovered two issues when parsing dates with the format 'MD,Y' (ex: 'january12,2001')

One of these issues is a duplicate of a currently open issue, while the other is new and could potentially negatively affect users.

1. Throws a ParseError when the year is 3 digits

Ex/

The following does not throw an error:
parser.parse("april2,2021")
parser.parse("april2,87")

However, the following throws a ParseError:
parser.parse("april2,785")

2. Incorrectly parses the year

This issue is a duplicate of the following: #1191

Some parse outcomes with the format specified will correctly parse the month and date, but not the year. The year will always default to the current year

Ex/

March1,3560 results in 3560-03-01 00:00:00 and is correctly parsed.

However, January15,7626 results in 2023-01-15 00:00:00 (incorrect).
