feat: support dynamic extra semantic release plugins

Added a new input (`semanticReleasePlugins`) to allow specifying
extra semantic-release plugins at runtime. These plugins are installed
dynamically (with `yarn add`) based on workflow call. Added `cosmiconfig`
dependency to read correct semantic release config file. Moved
`executeCommand` into a separate file for reusability in `main.js` file.
