Typo "criterias" in lib/zold/wts.rb line 140 breaks the typos CI step #63

The YARD comment above Zold::WTS#find at lib/zold/wts.rb:140 reads "All criterias are regular expressions". criterias is not an English word — the plural of criterion is already criteria, so the source carries a typo in a docstring exposed to RubyDoc and to anyone reading the SDK.

The crate-ci/typos GitHub Action picks the misspelling up on every push and exits with code 2, leaving the typos check red on master (see https://github.com/zold-io/zold-ruby-sdk/actions/runs/27216167649/job/80358119087, log line error: criterias should be criteria). The same job is red on the latest master commit 7c79029 and on every open pull request, so contributors cannot tell a real CI failure from this one.

Replace criterias with criteria on lib/zold/wts.rb:140. The grammar of the rest of the sentence still works because the original the criteria two words earlier is already the correct plural noun.
