organize project

[asandikci]

• new issue templates
• new pr templates
• security policy
• more labels
• update CI for releases (I know current CI is really bad written...)
  • select branches (text/textbox input), per line or separated with commas (defaults are master and extended branches)
  • type: debug or release (default is release)
  • release type: release or pre-release (default is pre-release)
  • maybe requires some changes in build.gradle file ?
  • note: test releases if there is a compatibility issue with Obtainium
• new CIs to organize/close/stale issues/PRs
• add wiki section about project structure and components (after I understood the project ofc lol)
