Fixed: Inconsistent Field Label Display on Task Side Panel (#5687)

Now all the required fields are displayed with the respective labels.

- Added a `FieldContextProvider` for the field `Reminder` in the
`ActivityEditorFields`.
- Fixed the missing label values, by adding a missed optional
`showLabel` within the `fieldDefinition` in the `useFieldContext`.

fixes: #5667
