fix(typescript, ci): standardize GitHub repo URL format and simplify local vs remote parity workflow

[jsklan]

Description

Updates the TypeScript generator to use git+https:// format for GitHub repository URLs in generated package.json files, ensuring local generation output matches remote generation.

Also cleans up the remote vs local generation parity test workflow by removing unused steps and adding a configurable branch input for manual runs.

Changes Made

• TypeScript generator: Changed getRepoUrlFromUrl to output git+https:// format instead of github: shorthand for GitHub URLs
• CI workflow: Added branch input for manual workflow runs, removed unused git-based change detection (the command already fails on diff)

Testing

• Manual testing completed
• Verified local and remote generation now produce matching output
