XSS potential in rendered Markdown fields (comments, description, notes, etc.)

### Impact All users of Nautobot versions earlier than 1.6.10 or 2.1.2 are potentially impacted. Due to inadequate input sanitization, any user-editable fields that support Markdown rendering, including: - `Circuit.comments` - `Cluster.comments` - `CustomField.description` - `Device.comments` - `DeviceRedundancyGroup.comments` - `DeviceType.comments` - `Job.description` - `JobLogEntry.message` - `Location.comments` - `Note.note` - `PowerFeed.comments` - `Provider.noc_contact` - `Provider.admin_contact` - `Provider.comments` - `ProviderNetwork.comments` - `Rack.comments` - `Tenant.comments` - `VirtualMachine.comments` - Contents of any custom fields of type `markdown` - Job class `description` attributes - The `SUPPORT_MESSAGE` system configuration setting are potentially susceptible to cross-site scripting (XSS) attacks via maliciously crafted data. ### Patches Fixed in Nautobot versions 1.6.10 and 2.1.2. ### References https://github.com/nautobot/nautobot/pull/5133 https://github.com/nautobot/nautobot/pull/5134
