Upgrade pyasn1 and pyasn1-modules dependencies (#504)

## Summary
This PR upgrades the pyasn1 and pyasn1-modules dependencies to newer
versions across the project.

## Key Changes
- Updated `pyasn1` from 0.5.1 to 0.6.2 in main requirements.txt
- Updated `pyasn1-modules` from 0.3.0 to 0.4.2 in main requirements.txt
- Added explicit `pyasn1>=0.6.2` constraint in enforcer/requirements.txt
to ensure compatibility

## Details
These upgrades bring in bug fixes and improvements from the pyasn1
library. The enforcer module now explicitly declares its minimum pyasn1
version requirement to ensure it receives the necessary updates.
