Unpin cryptography and pact-python pins

[UsamaSadiq]

Description

• Issue Upgrade Requirements action broken on snowflake-connector-python #37417 identified the make upgrade build as broken due to underlying cffi dependency issue of snowflake-connector-python.
• Since the new release of snowflake-connector-python was pending, to fix the upgrade job temporarily, both cryptography and pact-python packages were pinned (both have conflict with the cffi sub-dependency).

TODO

• Unpin both cryptography and pact-python constraints when snowflake-connector-python==4.0.0 is released.
• Track SNOW-2350569: snowflake-connector-python can't be installed with the latest version of cryptography snowflakedb/snowflake-connector-python#2541 for new release with the fix.

@UsamaSadiq I can work on it

[UsamaSadiq]

@himanshu-sharmav new version is now available so this should be a straightforward fix. snowflakedb/snowflake-connector-python#2541 (comment).

I've assigned the issue to you. You can ping me if you need any help at any point.

FYI, snowflake-connector-python 4.x has since been released, and openedx-platform already removed both of these pins a few weeks ago.
