Add format option to SchemaApplyParams

[ibrhmkoz]

params.Format is missing, thwarting us from providing a migration tool agnostic API.

// SchemaApplySlice runs the 'schema apply' command for multiple targets.
func (c *Client) SchemaApplySlice(ctx context.Context, params *SchemaApplyParams) ([]*SchemaApply, error) {
	args := []string{"schema", "apply", "--format", "{{ json . }}"}
	if params.Env != "" {
		args = append(args, "--env", params.Env)
	}
	if params.ConfigURL != "" {
		args = append(args, "--config", params.ConfigURL)
	}
	if params.URL != "" {
		args = append(args, "--url", params.URL)
	}
	if params.To != "" {
		args = append(args, "--to", params.To)
	}
	if params.DryRun {
		args = append(args, "--dry-run")
	} else {
		args = append(args, "--auto-approve")
	}
	if params.TxMode != "" {
		args = append(args, "--tx-mode", params.TxMode)
	}
	if params.DevURL != "" {
		args = append(args, "--dev-url", params.DevURL)
	}
	if len(params.Schema) > 0 {
		args = append(args, "--schema", strings.Join(params.Schema, ","))
	}
	if len(params.Exclude) > 0 {
		args = append(args, "--exclude", strings.Join(params.Exclude, ","))
	}
	args = append(args, params.Vars.AsArgs()...)
	return jsonDecodeErr[SchemaApply](newSchemaApplyError)(c.runCommand(ctx, args))
