Implement Core GitHub Actions for Issue Management

[snobbee]

Define and implement core actions for interacting with GitHub issues within the GitHub Plugin, including CREATE_ISSUE, MODIFY_ISSUE, and ADD_COMMENT. Each action handler should leverage the GitHub API to perform the respective operation, ensuring seamless interaction between Eliza and GitHub. These actions are essential for making Eliza capable of contributing directly to GitHub project management.
