Updates scripts for gh

[TomKovac]

This pull request includes several updates to various PowerShell scripts to enhance functionality and improve error handling. The most important changes include the addition of parameters, improved error messages, and enhanced script logic for handling GitHub issues and branches.

Enhancements to issue and branch management:

• scripts/_change_state.ps1: Added parameters and logic to handle issue state transitions in GitHub projects using GraphQL. This includes fetching project IDs, validating column names, and moving issue cards between columns.
• scripts/_create_issue_branch.ps1: Introduced a new parameter doNotCheckOldColumnName, added logic to ensure the script is run from the dev branch with no uncommitted changes, and integrated _change_state.ps1 to update issue states. [1] [2]

Error handling and validation improvements:

• scripts/create_new_issue.ps1: Added input validation for issue title and body, ensuring they are not empty, and updated the script to call _create_issue_branch.ps1 with the new parameter. [1] [2]
• scripts/ready_for_review.ps1: Added checks to ensure the working tree is clean before marking a branch as ready for review, and integrated _change_state.ps1 to update issue states accordingly.

Additional script enhancements:

• scripts/_is_on_dev_nothing_to_commit.ps1: Added logic to check if the current branch is dev and if there are uncommitted changes, providing clear messages for the user.
• scripts/commit_and_ready_for_review.ps1: Updated the script to change the working directory to the parent directory before committing changes to ensure all relevant files are included.

I would not pollute ixc with this.
We can use semantic model for that in a dedicated tooling, as we do for the documentation and resx compilers.

Keep the modifications to the scripts as it is, but remove the modifications to Program.cs.
