refactor(ast/estree): alter Program start span with converter

[overlookmotel]

#10134 fixed the start span of Program in TS AST to align with TS-ESLint.

Change the method this is achieved by - use a custom converter instead of mutating the AST in to_estree_ts_json and to_pretty_estree_ts_json. This method is more convoluted, but I think it's preferable if serialization does not have side effect of mutating the AST.
