simple-uptime-check does not have custom_content_type variable

[cwallace-omg]

TL;DR

As the title suggests, the simple-uptime-check module does not have a variable for the custom_content_type attribute of the google_monitoring_uptime_check_config resource. The attribute is described here:
https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/monitoring_uptime_check_config#custom_content_type-1

Without support for this attribute, certain uptime checks are impossible to configure properly when using this module.

Expected behavior

The simple-uptime-check module has a custom_content_type variable and uses it as part of the google_monitoring_uptime_check_config configuration.

Observed behavior
