Niraj Nandre 0cd3f16f87 feat(prebuilt/cloud-sql-mysql): Add env var support for IP Type (#1232) (#1347)
This PR fixes #1232 by allowing the `CLOUD_SQL_MYSQL_IP_TYPE`
environment variable to control the connection type for the
`cloud-sql-mysql` prebuilt tool, defaulting to "PUBLIC".

**Changes:**

* **`internal/prebuiltconfigs/tools/cloud-sql-mysql.yaml`:** Updated
`ipType` to use `${CLOUD_SQL_MYSQL_IP_TYPE:PUBLIC}`.
* **`internal/sources/cloudsqlmysql/cloud_sql_mysql.go`:** Removed
`validate:"required"` from the `IPType` field in the `Config` struct to
allow the default to be used when the env var is unset.
* **Documentation:** Updated relevant documentation to reflect the new
`CLOUD_SQL_MYSQL_IP_TYPE` environment variable usage.

**Testing:**

Built a local Docker image and tested on a GCE VM:

*   Setting `CLOUD_SQL_MYSQL_IP_TYPE="private"` connects via Private IP.
*   Setting `CLOUD_SQL_MYSQL_IP_TYPE="PUBLIC"` connects via Public IP.
*   Leaving `CLOUD_SQL_MYSQL_IP_TYPE` unset defaults to Public IP.

All tests initialized the toolbox successfully.

Fixes #1232
