Getting an error parsing rstudio-release.json due to invalid comment in json-file

[kvikende]

Commit https://github.com/cderv/r-bucket/commit/73cd034689383a03eb07c09f664095f7cfcb2fd4 added a javascript style block comment in the .json file, however the json spec does not allow for any comments which cause the json parser to not being able to parse the file.

Additionally, it introduced a trailing comma which is also not allowed according to the json spec.
