ts2fable merges documentation for member overloads resulting in too many parameters

Start by reproducing the reported output with the TypeScript overload snippet and trace how member overloads receive JSDoc and parameter metadata. The fix is complete when the generated F# documentation is attached appropriately to the overloads, includes only applicable parameters, and no longer produces warnings for this case.

given the following TS:

        /**
         * Register a signature help provider.
         *
         * Multiple providers can be registered for a language. In that case providers are sorted
         * by their {@link languages.match score} and called sequentially until a provider returns a
         * valid result.
         *
         * @param selector A selector that defines the documents this provider is applicable to.
         * @param provider A signature help provider.
         * @param triggerCharacters Trigger signature help when the user types one of the characters, like `,` or `(`.
         * @param metadata Information about the provider.
         * @return A {@link Disposable} that unregisters this provider when being disposed.
         */
        export function registerSignatureHelpProvider(selector: DocumentSelector, provider: SignatureHelpProvider, ...triggerCharacters: string[]): Disposable;
        export function registerSignatureHelpProvider(selector: DocumentSelector, provider: SignatureHelpProvider, metadata: SignatureHelpProviderMetadata): Disposable;

ts2fable 0.8.0-build.616 generates the following F#:

            /// <summary>
            /// Register a signature help provider.
            /// 
            /// Multiple providers can be registered for a language. In that case providers are sorted
            /// by their <see cref="languages.match">score</see> and called sequentially until a provider returns a
            /// valid result.
            /// </summary>
            /// <param name="selector">A selector that defines the documents this provider is applicable to.</param>
            /// <param name="provider">A signature help provider.</param>
            /// <param name="triggerCharacters">Trigger signature help when the user types one of the characters, like <c>,</c> or <c>(</c>.</param>
            /// <param name="metadata">Information about the provider.</param>
            /// <returns>A <see cref="Disposable" /> that unregisters this provider when being disposed.</returns>
            abstract registerSignatureHelpProvider: selector: DocumentSelector * provider: SignatureHelpProvider * [<ParamArray>] triggerCharacters: string[] -> Disposable
            abstract registerSignatureHelpProvider: selector: DocumentSelector * provider: SignatureHelpProvider * metadata: SignatureHelpProviderMetadata -> Disposable

the problem here is that the TS intended for the jsdoc to contain the superset of parameters for both overloads, but that superset has only been attached to the top overload in F#. it also has all parameters, which causes warnings.
