NOTE: Sass and Bower deprecations

• This is the last release where both LESS and Sass are going to be updated, barring anyone submitting a PR to handle Sass maintenance. I much prefer Sass, but LESS is in a better spot in this project and has been the primary tested build. I sadly just need to save time where I can and maintaining 2 CSS extensions. v4 will be all Sass or just pure CSS.
• I also deleted the bower.json file as this wasn't used in a very long time.

Added

• Lorwyn Eclipsed (ECL) and Commander (ECC) set symbols (#283)
• Avatar: the Last Airbender Eternal (TCE) set symbol (#278)
• Teenage Mutant Ninja Turtles (TMT), TMT Source Material Cards (PZA), and TMT Eternal Legal Cards (TMC) set symbols (#284)
• Alias of y25 for yeoe (#281)
• Strixhaven Mystical Archives Japan promo set symbol, using STA-JPN as the set code (#276)
• New Github Actions workflows for handling the documentation website and PR previews.

Changed

• TLA set symbol now uses the official one; there is no need to have a standalone glyph either, the regular rarity is now the default set symbol (#286)

Fixed

• Typo for TLA set code in Sass map (#277)
• SPE name in documentation is now the corrected with the "Eternal-Legal" ending (#282)
