feat: add missing PrivateLink URLs to datasource

[dgniewek]

Added additional outputs to snowflake_system_get_privatelink_config returned by DB, but not previously included in terraform datasource.

List of additional outputs:

• regionless_account_url
• regionless_snowsight_url
• snowsight_url
• internal_stage

Test Plan

• acceptance tests - passed locally, please run at PR level

@sfc-gh-swinkler may I ask for activating GH actions for this PR pls?

This looks fine, but i cannot find anywhere in the documentation where it says this function returns these values. https://docs.snowflake.com/en/sql-reference/functions/system_get_privatelink_config. If you could please explain where these come from, that would be helpful. In the meantime i will go ahead an merge since it won't cause any problems if the values are not found anyhow.

Hi,
Thanks for merging :)

Unfortunately, some of those options seem undocumented but helpful in further terraforming (creation of regionless-privatelink-account-url DNS record for example).

I got those parameters directly from SYSTEM$GET_PRIVATELINK_CONFIG() function output:

  "regionless-snowsight-privatelink-url": "app-snoworg-snowacc.privatelink.snowflakecomputing.com",
  "privatelink-account-name": "ab12345.eu-west-1.privatelink",
  "privatelink-internal-stage": "sfc-xxxxx.s3.eu-west-1.amazonaws.com",
  "privatelink-vpce-id": "com.amazonaws.vpce.eu-west-1.vpce-xxxxxxxxxxxxx",
  "snowsight-privatelink-url": "app.eu-west-1.privatelink.snowflakecomputing.com",
  "privatelink-account-url": "ab12345.eu-west-1.privatelink.snowflakecomputing.com",
