Support for deno.jsonc

[maximilian-hammerl]

Is your feature request related to a problem? Please describe.

An incorrect part of the Supabase documentation mentioned, that the edge functions support deno.jsonc files which they, it turns out, do not support: supabase/cli#3050

Therefore, I want to request support for deno.jsonc as a new feature for the edge runtime.

Describe the solution you'd like

Similar to how Deno already supports deno.jsonc files, it would be helpful if the Supabase edge functions also supported JSONC-specific features such as line and block comments.
