Rename outdated po files

@greyli @vlevieux @Jalkhov Coordinators, and @Abdur-rahmaanJ, I just create a tool to rename outdated po files. sometimes Flask maintainers remove some docs but translations still have these po files, in one of the PRs(https://github.com/flaskcwg/flask-docs-fa/pull/40), a contributor translates some outdated documents And that's why I thought we need something to remove/rename outdated po files.

repo: https://github.com/mmdbalkhi/pochecker

install:

git clone https://github.com/mmdbalkhi/Pochecker.git
cd Pochecker && python3 setup.py install

usage:

pochecker --help

pochecker -p docs/ -e rst
