Update `installModels` to go through the v2 API endpoints

Lines 26 to 41 in fdbf90d

	async installModels(database: string, engine: string, models: Model[]) {
	const action: InstallAction = {
	type: 'InstallAction',
	sources: models,
	};
	return await this.runActions(database, engine, [action], false);
	}
	async listModels(database: string, engine: string) {
	const action: ListSourceAction = {
	type: 'ListSourceAction',
	};
	return await this.runActions(database, engine, [action]);
	}

It's currently using the v1 actions API. It should instead be issuing an exec() query that loads the models, similar to this implementation of load_json in the julia SDK:
https://github.com/RelationalAI/rai-sdk-julia/blob/6c9ddf55fe791d82b15c8a9e9f80c0bcdec04064/src/api.jl#L650-L655

Ideally it should construct a query string + inputs, that would look something like either of these options:

query = `def insert:rel:catalog:model = model_insertions`;
inputs = {
    name: "model_insertions",
    value: models.map((m, index) => {
        [m.name, m.value],
    })
};

or like this (copied from the current Console code):

  models.forEach((m, index) => {
    const inputRelation = `__model_value__${index}__`;

    queryStrings.push(
      `def delete:rel:catalog:model["${m.name}"] = rel:catalog:model["${m.name}"]`,
      `def insert:rel:catalog:model["${m.name}"] = ${inputRelation}`,
    );
    queryInputs.push({
      name: inputRelation,
      value: m.value,
    });
  });

@denisgursky I've assigned this one to you, and put it at medium priority. It would be great to have this converted so that we can see a dent in our v1 vs v2 numbers 😭
