Support rebuild FastlaneSwiftRunner project on CI/CD platforms

[vnntsu]

Why

• Currently, we ignore the file FastlaneRunner which is containing executable commands for Fastlane.
• On CI/CD machine, it needs to rebuild the FastlaneSwiftRunner project to have the latest FastlaneRunner before doing any tasks.
• It could be a script, so Bitrise or GitHub Actions can use for rebuilding.

The issue seems to be because the flag --disable_runner_upgrades, we can run fastlane swift on CI without the flag.
I think what we need is a document for related the error when running locally without --disable_runner_upgrades and a guide on how to compile FastlaneRunner locally.

This commit I removed FastlaneRunner from git and remove the flag, FastlaneRunner compiles on CICD and the workflow runs smoothly.

@blyscuit Do you mean no need for any script to rebuild FastlaneRunner?

[blyscuit]

On CICD, we don't need the script because FastlaneRunner will be rebuild if we don't include the flag disable_runner_upgrades.
On local machine, I'm still figuring out why it is failing.
I think the only use for the script is for the local user to run it without opening the Xcode project for FastlaneRunner, but that'd be introducing a new point of failure ie: if the script fail because fastlane change its implementation with he script. So in the long run we shouldn't rely on the script. Still, adding it now wouldn't hurt.
