Fix pronunciation of combining circumflex (#18325)
Link to issue number:
Closes #17725
Summary of the issue:

U+0302 is now pronounced as "hat" in English.
Description of developer facing changes:
None
Description of development approach:
Replaced "normalizes" with "hat" in source/locale/en/symbols.dic.
