week_of_month returns 6, although months can only have 5 weeks max

• I am on the latest Pendulum version.
  pendulum==3.0.0
• I have searched the issues of this repo and believe that this is not a duplicate.
  There are no current open issues. The closest one I could find is one that was opened in 2020. Most of the issues with this property have to do with negative values; however this issue seems to be more about miscounting

• OS version and name: MacOS Sequoia
• Pendulum version: 3.0.0

Issue

Was playing around with the week_of_month property and found some interesting behavior:

The following:

err_dt = pendulum.datetime(2024, 9, 30, tz='America/Los_Angeles')
err_dt.week_of_month

Results in this output:

6

I'm a bit confused by this behavior and believe it should be a bug because September 2024 should have the following week breakdowns:

Week 1: September 1st, Sunday -> September 8th Sunday
Week 2: September 8th, Sunday -> September 15th Sunday
Week 3: September 15th Sunday -> September 22nd Sunday
Week 4: September 22nd Sunday -> September 29th Sunday
Week 5: September 29th Sunday -> September 30th Monday (last date in September)
