[2.22.0] "y" prononcé comme "i" — zéphyr rime enfin avec frémir

• 2.22.0 — Fixed a real gap in the rhyme engine: a bare "y" that IS the vowel itself (not a
  semi-consonant before another vowel, already handled separately) is pronounced exactly like
  "i" — "zéphyr"/"frémir", "rugby"/"pari", "martyr"/"sortir" — but "yr" and "ir" were staying
  two different keys for the same [iʁ] sound, so words spelled with a final "y" never matched
  their "i"-spelled rhyme partners. Found via a real poem (thank you, Alucard) using "zéphyr" as
  a rhyme for "frémir"/"souffrir" — confirmed correct by ear, wrong in the tool. Also worth
  noting for anyone who ran into this already: this fix had actually been written and tested
  earlier in the process of tracking the report down, but was left sitting in a working copy
  and never actually packaged into a release — this version is the first one that genuinely
  includes it, sorry for the runaround while we nailed down what was and wasn't shipped.
