[BUG] align_one language error with tokenizer

[Hocine958]

Debugging checklist

[ ] Have you read the troubleshooting page (https://montreal-forced-aligner.readthedocs.io/en/latest/user_guide/troubleshooting.html) and searched the documentation to ensure that your issue is not addressed there? [X] Have you updated to latest MFA version (check https://montreal-forced-aligner.readthedocs.io/en/latest/changelog/changelog_3.0.html)? What is the output of mfa version? [ ] Have you tried rerunning the command with the --clean flag?

Describe the issue When performing an "align_one" command on japanese files, the "language" passed to to "generate_language_tokenizer()" function (align_one.py line 156) is a string instead of enum, which causes the if in spacy.py at line 56 to be skiped and dict access at line 66 to throw a "KeyError: 'japanese'" exception.

For Reproducing your issue Please fill out the following:

1. Corpus structure
   • What language is the corpus in? -> japanese
   • How many files/speakers? -> 1
   • Are you using lab files or TextGrid files for input? -> txt file
2. Dictionary
   • Are you using a dictionary from MFA? If so, which one? -> japanese_mfa v3.0.0
   • If it's a custom dictionary, what is the phoneset?
3. Acoustic model
   • If you're using an acoustic model, is it one download through MFA? If so, which one? -> japanese_mfa v3.0.0
   • If it's a model you've trained, what data was it trained on?
