Highlight all PEP-0350 defined codetags

MagicPython currently only highlights a very small subset of the codetags from PEP-0350:

• NOTE: A note
• XXX: Attention
• HACK: A hack
• FIXME: Problematic code
• BUG: A bug
• TODO: Pending task

I think the full list should be included in MagicPython, or at least the rest of the top-level mnemonics:

• NOBUG
• REQ
• RFE
• IDEA
• ???
• !!!
• PORT
• CAVEAT
• FAQ
• GLOSS
• SEE
• TODOC
• CRED
• STAT
• RVD

• Editor name and version: Visual Studio Code v1.66.2
• Platform: Windows 10.0.19044
• Color scheme: Dracula
• MagicPython version: 1.1.0
• A sreenshot:
  
• 5-10 lines of surrounding code: Exhaustive list of mnemonics:

Comece localizando as definições existentes de realce de codetag do MagicPython e compare-as com a lista de mnemônicos do PEP-0350 no issue. Estenda a lista reconhecida para abranger os mnemônicos de nível superior solicitados e, em seguida, execute os testes de realce de sintaxe do projeto ou inspecione comentários Python realçados para verificar as novas tags.
