parseCompilerLogOutput crashes when first error is graphql deprecation warning

Hi Folks.
Found a case here.
given a codebase using rescript-apollo, with a deprecated field warning, the parser will fail its "File " branch based on the next line not being Warning, and end up in its last case where it attempts to push a follow up line to an empty parsedDiagnostics array.

I can see some pushback on the apollo output here maybe, but would it be better to make the "File " branch more permissive, or allow a new parsed diagnostic to be created there in that non-empty-line case?

Thanks
Alex
