Documentation Grammar Fixes Changes by File

[donatik27]

1. docs/docs/noir/standard_library/meta/typ.md
   Old text:
   "for a trait constraint specified from a where clause is unknown,"
   New text:
   "for a trait constraint specified in a where clause is unknown,"
   Reason: Corrected preposition usage from "from" to "in" as it's more appropriate when referring to clauses in programming contexts.

2. docs/docs/noir/standard_library/meta/index.md
   Old text:
   "The result of the field operations are passed into this function for any final processing."
   New text:
   "The result of the field operations is passed into this function for any final processing."
   Reason: Fixed subject-verb agreement. "Result" (singular) requires "is" rather than "are".

3. docs/docs/noir/standard_library/meta/trait_def.md
   Old text:
   "This function is useful for cases where the compiler may fails a type check"
   New text:
   "This function is useful for cases where the compiler may fail a type check"
   Reason: Corrected verb conjugation. After modal verb "may", the base form of the verb "fail" should be used.
