Update badges, CI and coveralls reporting (#29)

* Update `.coveralls.yml` to point to `semaphore`
* On `.semaphore/semaphore.yml`:
    * Rename pipeline to `Run specs in all supported rubies'
    * Extract `checkout` command to `global_job_config.prologue`
    * Add `3.2.2`, `3.1.4`, `3.0.6`, `2.7.8` tasks
    * Correctly configure main `3.2.2` task to publish test report, now being picked up by Semaphore 
![Screenshot 2023-05-09 at 4 55 13 PM](https://github.com/gonzedge/rambling-trie/assets/218312/de876e83-f569-48b9-b2f1-4a33c8c166c5)
    * Remove unnecessary formatters from non-`3.2.2` tasks
* On badges:
    * Change `README.md` to have one badge per line instead of all in one giant line
    * Add RubyGems downloads badge
    * Add CodeClimate issues badge
    * Update docs badge to point directly to [rubydoc.info/gems/rambling-trie](http://rubydoc.info/gems/rambling-trie)
    * Update license badge to one from shields.io
