[api-extractor] Incorrect indentation

[rudolf]

Source code:

export interface I18nSetup {
  Context: ({ children }: { children: React.ReactNode }) => JSX.Element;
}

src.d.ts:

export interface I18nSetup {
    Context: ({ children }: {
        children: React.ReactNode;
    }) => JSX.Element;
}

api documentation signature code block:

Context: ({ children }: {
        children: React.ReactNode;
    }) => JSX.Element;

This seems to be caused by stripping the indentation from . Context: ( in the d.ts file, but not stripping the same amount of indentation from the subsequent lines.

Ideally api-extractor/documenter should use 2-space indentation as this seems to be the most common convention for typescript source code.

This can probably be fixed up using Span.getIndent().

Longer term, I'd prefer to implement a lightweight pretty-printer that we could apply to the API signature snippets to allow more flexible indentation and word-wrapping.
