fix: bump pycountry version in ERPNext to be compatible with the frappe one

[FHenry]

Actual result of
bench setup requirements failed on develop branch (frappe and ERPNext)

/workspace/development/frappe-bench$ bench setup requirements

$ /workspace/development/frappe-bench/env/bin/python -m pip install --quiet --upgrade -e /workspace/development/frappe-bench/apps/frappe 

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
erpnext 16.0.0.dev0 requires pycountry~=22.3.5, but you have pycountry 24.6.1 which is incompatible.

Since frappe/frappe@81b8b84b commit (ping @barredterra) the version is 24.6.1 in frappe

May be a another fix can be to remove this dependencies in ERPNext as it is already provided by Frappe ?
