Additional context

The error no longer shows up, but that's because we simply ignore the included Microsoft Bicep repo as a quick fix. We should have a deeper look at what's causing it.

[SimonWahlin]

Problem seems to be that mcr.microsoft.com responds with a HTML page that the ACR SDK tries to parse as JSON.

The bicep language server is downloading a module index which is uses for completions, the cache is dowloaded by the method private async Task<ImmutableArray?> TryGetModulesLive()

We might want to implement something similar in the future, until then, just ignoring MCR is good enough for now.
