fix(admin-ui): Prevent comma decimal separator from converting inputs to NaN (#5566)

**What**
- Using the Price List bulk editor with a locale that uses comma as the decimal separator would convert decimal numbers to NaN. This PR fixes that by replacing commas with dots, before passing the values on to the state manager.

Closes #5565
