Add section header to lora formats of flux canny and depth

[christian-byrne]

Problem

• The flux depth/canny template workflows have a Note node that links to the start of the Flux canny and depth section of the docs here.
• However, one of the template workflows is for the lora format of the depth flux model
• When trying that template, the user clicks the link in the Note node and gets directed to the top of the section. Instead of scrolling down, the user sees the first text and thinks they need the flux depth dev model, instead of scrolling down and seeing that they only need to download the lora format and change the value in the LoraLoaderModelOnly node.

Proposed Solution

• Create a section header above the lora format section
• There's then a hyperlinkable anchor
• The flux depth lora format template workflow can be adjusted to link directly to that section, preventing this common user headache
