Simplify ci to be integrated into sast-ide-integration

What does this MR do?

• A local script for local testing
• Optimise the CI script, and reuse the local script
• Remove all the redundant lsp prefix from the names of the CI jobs
• Infer the test image using git ls-tree
• Remove the unnecessary runway job and run-local_cmd job
• Remove unnecessary configuration items from config.yml
• Updated README.md
• Removed a few deprecated files like curl.go and go.mod since the bash script is used for local testing
