2692: Slight changes for prometheus metrics r=Kerollmops a=gmourier

# Pull Request

## What does this PR do?

- Replace "MeiliSearch" with "Meilisearch"
- Brings some consistency between rust identifier and exposed metrics names
- Add suffix describing unit, in plural form. e.g `MEILISEARCH_DB_SIZE_BYTES` (https://prometheus.io/docs/practices/naming/#metric-names)
- Update dashboard.json
