Update mypy to 1.11.0

[meghprkh]

Please upgrade to mypy v1.11 as it has a lot of new features from the currently used version of 1.8 and will help with devx quite a lot!

The following bash script is being used:

#!/bin/bash

podman pull python:3.8-alpine
podman run -v .:/workspace:rw -i python:3.8-alpine /bin/sh << EOF
#!/bin/sh
python --version
pip install pip-tools
cd /workspace/
pip-compile --generate-hashes --resolver=backtracking --upgrade ./requirements.in
EOF

VERSION=$(cat requirements.txt | grep 'mypy==' | sed 's/[^0-9.]*//g')
sed -i "s/mypy=[0-9.]*/mypy=${VERSION}/g" README.md

@meghprkh Would you be able to address the merge conflicts?

[meghprkh]

I have redone #309 so that there is no conflict in #313. Would it be possible to force-push and remove the latest commit and merge #311 and #313 in order? Again extremely sorry for the inconvenience.
