Changes to Textmate scopes

Describe the bug
With v2.8.5, textmate scopes have changed and many tokens only have the 'source.r' scope (related to Rsyntax upgrade?). As a result, themes and customisation are affected with limited ability to fine tune.

To Reproduce

1. Before upgrading to 2.8.5, observe that object on the left hand side of <- (e.g. dt <- data.table()) have two textmate scopes - variable.other.r and source.r
2. Upgrade to 2.8.5
3. Only 1 textmate scope left - source.r

Can you fix this issue by yourself? (We appreciate the help)

Yes / [No]

Expected behavior
Behaviour prior to upgrade where tokens have multiple textmate scope to fine tune customisation.

Environment (please complete the following information):

• OS: macOS
• VSCode Version: 1.99.2
• R Version: 4.4.2
• vscode-R version: 2.8.5

Thanks

Riproduci la differenza degli scope usando vscode-R 2.8.5 con l’esempio R segnalato, confrontandola con il comportamento precedente all’aggiornamento. Traccia il percorso di generazione degli scope di TextMate o di aggiornamento di Rsyntax responsabile della modifica. Il lavoro è completato quando token come l’oggetto a sinistra di <- recuperano gli scope variable.other.r e source.r previsti e viene ripristinata la personalizzazione del tema.
