Remove divBasedFormLayout from jelly files

Jenkins minimum version is now 2.375.4, the conditional is always true.

Testing done:

• Modified the updated jelly files and confirmed that I saw each of the modified pages during my testing (debugging strings added temporarily, removed before final commit)
• Defined a freestyle job and confirmed it ran as expected without access control enabled
• Defined a Pipeline job and confirmed it ran as expected without access control enabled
• Enabled access control for builds and allowed "Run as Specific User", "Run as User who Triggered Build", and "Run as anonymous". Confirmed that the setting was honored in the freestyle job and the Pipeline job

Testing detected a mismatched div tag. That was fixed during testing.
