fix: Fixed FileWidget to work across all themes

Fixes rjsf-team#2095 by making `FileWidget` use the `BaseInputTemplate` for rendering the file input
- Updated `@rjsf/utils` to fix two small bugs found while fixing the issue:
  - `dataURItoBlob()` was updated to deal with parsing errors in `atob()` with malformed URL and to decode the name to a human-readable string
    - Added additional tests to verify the fixes
  - `replaceStringParameters()` was updated to split using a regex to deal with situations where the params themselves contain replaceable character identifiers
    - Added an additional test to verify the bug was fixed
- Updated `@rjsf/core` to switch `FileWidget` so that it uses the `BaseInputTemplate` to render the input, passing a new `onChangeOverride` function to deal with file events
  - Updated `BaseInputTemplate` to favor `onChangeOverride` rather than the default `onChange` handler it builds
- Updated the `BaseInputTemplate` in all of the themes to also favor `onChangeOverride` if specified over the default `onChange` handler
  - Updated the snapshots in all themes to reflect the improved `FileWidget` use of `BaseInputTemplate` in all themes
- Updated `@rjsf/bootstrap-4` to delete the `FileWidget` in favor of the improved `core` one
- Updated `@rjsf/material-ui` and `@rjsf/mui` to have the `BaseInputTemplate` support the automatic `shrink` of the label when the `type` of the input is `date`, `datetime-local` and `file`
  - Also removed the `DateWidget` and `DateTimeWidget` in both themes since they were only providing the `shrink` behavior which is now encapsulated in `BaseInputTemplate`
- Updated the `CHANGELOG.md` file accordingly
