SNOW-3995071: PAT to support path expansion #3006

What is the current behavior?

token_file_path = "~/.snowflake/pat.token"

Error: [Errno 2] No such file or directory: '~/.snowflake/pat.token'

What is the desired behavior?

Allow token_file_path to support tilde shortened home directory, similar to private_key_file.

How would this improve snowflake-connector-python?

It will allow re-using home shortened paths within connections.toml when using devcontainers in docker locally, such as a map (bind mount) ~/.snowflake to the containers internal user /root/.snowflake.
