Select mirrord.json as default config choice

Now it there are multiple files in .mirrord folder named *mirrord.json it's not clear which one will be used.

mirrord-vscode/src/config.ts

Line 205 in f8acc3b

private static async getDefaultConfig(folder: vscode.WorkspaceFolder): Promise<vscode.Uri | undefined> {

In my case I have multiple files in that folder one named __mirrord.json, that was being used while I was expecting mirrord.json to be used.
I guess one option is to choose mirrord.json file over others containing mirrord, or document this somewhere.

I think we should restrict the regex to mirrord.{json/yaml/toml} for default config

I guess the only risk there is for people who don't have mirrord.{json/yaml/toml} but something like *mirrord, so for them it will stop working when upgrading.

The plugin sorts default config candidates using String.localeCompare and always picks the first one from the list. We should document it somewhere
