Inconsistent months data for date conversion

[aj3sh]

We have noticed inconsistencies in the monthly data across Hamro Patro and Nepali Patro, starting from the year 2081. This inconsistency was initially highlighted in the go-nepali project (opensource-nepal/go-nepali#15). The issue was addressed in this project through PR #79. However, this PR only fixes the data for the year 2081.

After a thorough examination, here's what I discovered:

• Hamropatro has incorrect data for the year 2087, with 367 days in a year.
• The data pattern of the Baishakh from Nepali Patro appears to follow a specific pattern and is likely to provide accurate information.

Here are the data from different sources:
