2.54.0 package is larger than 2.53.0

This size increase is observed on MSI and DEB:

Not sure if this is caused by #26749.

In Windows, the CLI2 folder size is 218MB in version 2.53.0 and increases to 305MB in version 2.54.0.
While Python3.11 binary slightly enlarges the overall size, the significant change occurs in site-packages(200MB -> 281MB).

The cause of this issue is that the file size of .pyc files have significantly increased in Python 3.11

Python 3.11 made .pyc files almost twice as large. There are two main reasons for this:

PEP 659 made the bytecode stream ~3x as large as 3.10.
PEP 657 made the location tables ~9x as large as 3.10. ---python/cpython#99554

For example, paramiko and PyGithub remain the same version but the size grows about 50%.

Python 3.12 might alleviate this issue.
