Use .R (not .r) as default R file extension

[ThomasSoeiro]

• VS Code Version: 1.106
• OS Version: Fedora Linux 41 and Windows 11

Steps to Reproduce:

1. Create a New File (Ctrl + N)
2. Select the R language (Ctrl + K M and select R)
3. Save the file (Ctrl + S)
4. The default file extension is .r

The default file extension should be .R (not .r), as used in R source and other R IDEs (e.g. RStudio and Positron), and as recommended in the Tidyverse Style Guide.

Another user has already asked that on StackOverflow.
