Fix MR Modal Vulnerability Links Overflow Modal

What does this MR do?

This MR fixes that the links [and identifiers] in the vulnerability modal (used in the pipeline security page) can overflow the modal. It is fixed by adding the gl-word-break-all CSS class to both places.

It is unlikely that an identifier will overflow though.

Relates to #242035 (closed).

Steps to test

1. Open a pipeline which found vulnerabilities.
2. Open a vulnerability in the Security tab which has a link [or identifier] that contains a lot of alphanumeric characters without any other characters (e.g. a SHA256 hash). If you don't have a vulnerability with such a link, you can either create one or go the lazy way and simulate it by replacing the links computed value with the following snippet:

links() {
  return [
    {
      url:
        'https://gitlab.com/gitlab-examples/security/security-reports/-/commit/f34619f924ba08039cf3932853695b8cae737ef1f34619f924ba08039cf3932853695b8cae737ef1',
    },
  ];
  // return this.asNonEmptyListOrNull(this.vulnerability.links);
},

3. Check that the link overflows the modal.
