SaaS Connector Template Creation Fix: Integer fides_key

[pattisdr]

Purpose

We want to have the same identifier used across a saas config and dataset config but integer keys were not accounted for.
Spotted by @chriscalhoun1974 - he created a saas connection config from a template in testing and gave it an "instance_fides_key" of "111". This is saved as a string type on the DatasetConfig.fides_key but is interpreted as an integer when parsing the yaml. This throws a validation error later when you try to edit the dataset, and we see that the datasetconfig.fides_key field does not match the fides_key in the saas config.

Changes

• Use quotes to force a string when replacing <"instance_fides_key"> in the saas config and dataset config yaml.
