Docs: typo on "frequent"

I replaced "high frequent terms" with "high frequency terms" and "low frequent terms" with "low frequency terms".

Alternatively, we could write, "highly frequent terms" and "minimally frequent terms" (or just "rare terms").

Closes #8962

 This query allows handling `stopwords` dynamically at runtime, is domain
 independent and doesn't require on a stopword file. It prevent scoring /

 the query terms are above the given `cutoff_frequency` the query is
 automatically transformed into a pure conjunction (`and`) query to
 ensure fast execution.
