Description

1. Customer had an issue with a webhook URL that had previously worked when we had no front-end validation of the URL field in Generic Webhook integration form. After upgrading to a version that has the new form, they cannot edit or create new integrations. Based on a sanitized version, it appears that their URL was failing due to the presence of a % character, as part of URL encoding.
2. There have been other issues, on other forms' endpoint fields, where customers have used a variety of formats, including Kubernetes service names instead of traditional URL formats.

Rather than only address the immediate issue in #1 above, by adding % to the validation regex, I decided to allow for #2 as well. Therefore, I removed all specific validation, and just made the field required.
