style: add pre commit hook for style check and format

[lausannel]

This PR includes the following changes:

1. Add pre-commit-config.yaml for pre commit hooks.
2. Add github actions for style check
3. Format the current styles

[lausannel]

Before committing, format the code by running the following commands:

pip install pre-commit
pre-commit run --all-files

Note: It may take some time to initially download and install pre-commit hooks, and for dotnet format to check and format the source files.
