Localization effort

This an issue to keep track of which texts need to be provide translations and added to our localization feature

### texts that need translations
- text in LegislationOverview
- text in LegislationLatestVote
- Term's role title in PersonRoles.tsx : https://github.com/CouncilDataProject/cdp-frontend/blob/main/src/containers/PersonContainer/PersonRoles.tsx#L102
- text in the legislation card
- text in LazyFetchDataContainer, its use throughout the app -- in particular the `data` field of LazyFetchDataContainer
- `copy` and `share` text in share event at a timepoint feature (on the event page)
- `from` and `to` in the DateRangeFilter
- N `events` text that specifies how many search results there are in the `/events/search` page
- `Supervistor` constant (https://github.com/CouncilDataProject/cdp-frontend/blob/main/src/models/constants.ts#L8)
-

### texts that need to be localized (add to LocalizedStrings.tsx and the supported lang files)
-

### localization bugs
- fix use of `ROLE_TITLE` in PersonRoles.tsx to account for role titles that have spaces in them, e.g. Vice Chair. https://github.com/CouncilDataProject/cdp-frontend/blob/main/src/containers/PersonContainer/PersonRoles.tsx#L35
