Fix 'toes' being singularized to 'to'

[hangy]

Fixes #1100

Here is a checklist you should tick through before submitting a pull request:

• Implementation is clean
• Code adheres to the existing coding standards; e.g. no curlies for one-line blocks, no redundant empty lines between methods or code blocks, spaces rather than tabs, etc.
• No Code Analysis warnings
• There is proper unit test coverage
• If the code is copied from StackOverflow (or a blog or OSS) full disclosure is included. That includes required license files and/or file headers explaining where the code came from with proper attribution
• There are very few or no comments (because comments shouldn't be needed if you write clean code)
• Xml documentation is added/updated for the addition/change
• Your PR is (re)based on top of the latest commits from the dev branch (more info below)
• Link to the issue(s) you're fixing from your PR description. Use fixes #<the issue number>
• Readme is updated if you change an existing feature or add a new one
• Run either build.cmd or build.ps1 and ensure there are no test failures

@hazzik I reviewed my original change and noticed that the singularization bug would also affect other words with only one char leading before "oe"/"oes" (ie. "doe"/"does" or "woe"/"woes"). I changed the rule accordingly.

What about roe? 🤣

😲 That looks complicated. Do we have any rule about nouns with more than one meaning and different inflection rules?

Looks like this needs to be rebased after one of the other PR's merged.

Yes, I anticipated it, but wasn't sure which would be merged first. Rebase done. 🙂

Is this ready to go?
