Improve generation script

[WilliamBergamin]

Summary

This PR aims to improve the generation script by providing a more stable command to look up changed file after generating the typescript files.

In the last scheduled generation the script was unable to recognize that their were more then one changed files and did not created a PR for the generated files.

Testing:

1. Pull this repo
2. Make a change in src/connectors/mod.ts
3. run the following sh command [[ $(git ls-files --other --modified --exclude-standard) == "src/connectors/mod.ts" ]] && { echo "No real changes. Do not commit."; exit 1; } -- the output should "No real changes. Do not commit."
4. Make a change in another file in the repo
5. run the following sh command [[ $(git ls-files --other --modified --exclude-standard) == "src/connectors/mod.ts" ]] && { echo "No real changes. Do not commit."; exit 1; } -- their should be no output

This generation GitHub action was triggered from this branch and shows that the changes work.
