Misses "to many [plural noun]" -> "too many [plural noun]" and other "to" --> "too" errors

# Examples:
"Too" (misspelled as "to") is always an adjective here and must be corrected
1. "There are to many berries." (remove "berries" and it works)
1. "To many people and the boat may sink."
1. "He likes to many types of chili peppers."
1. "To little effort was put into the project."
1. "We have to much food!" (LanguageTool detects this)
1. "To little"
1. "To loud"
1. "Is she **to** angry to read this?" (LanguageTool detects this)

# Edge cases:
Here "to" is a preposition which should not be corrected to "too".
1. "To many the world is beautiful."
1. "To few the chair is comfortable." (LanguageTool incorrectly suggests "to" --> "too"!)
1. "To many people live on Earth." (ambiguous as pointed out in [a comment](https://github.com/Automattic/harper/issues/3939#issuecomment-5155946914))

Start with issue #3939's examples and edge cases, then locate the existing grammar-rule entry point and its related tests. Check the reported positive cases alongside the prepositional and ambiguous cases; done means the intended “too” errors are detected without changing the documented exceptions.
