gh-35694: Correct spelling in permgroup_named: Diyclic => Dicyclic
    
<!-- Please provide a concise, informative and self-explanatory title.
-->
<!-- Don't put issue numbers in the title. Put it in the Description
below. -->
<!-- For example, instead of "Fixes #12345", use "Add a new method to
multiply two integers" -->

### 📚 Description

DiCyclic groups are defined in permgroups_named.py. In 3 places it is
misspelled. This PR corrects the misspelling.

(I think the preferred spelling would be Dicyclic, not DiCyclic, but
this PR does not change that.)

<!-- Describe your changes here in detail. -->
<!-- Why is this change required? What problem does it solve? -->
<!-- If this PR resolves an open issue, please link to it here. For
example "Fixes #12345". -->
<!-- If your change requires a documentation PR, please link it
appropriately. -->

]`. -->
