Remove jQuery AJAX from the repo editor (#29636)

Browse source 
# Preview Tab
- Removed the jQuery AJAX call and replaced with our fetch wrapper
- Tested the preview tab functionality and it works as before

# Diff Tab
- Removed the jQuery AJAX call and replaced with htmx
- Tested the diff tab functionality and it works as before

## htmx Attributes
- `hx-post="{{.RepoLink}}..."`: make a POST request to the endpoint
- `hx-indicator=".tab[data-tab='diff']"`: attach the loading indicator
to the tab body
- `hx-target=".tab[data-tab='diff']"`: target the tab body for swapping
with the response
- `hx-swap="innerHTML"`: swap the target's inner HTML
- `hx-include="#edit_area"`: include the value of the textarea (content)
in the request body
- `hx-vals='{"context":"{{.BranchLink}}"}'`: include the context in the
request body
- `hx-params="context,content"`: include only these keys in the request
body

# Demo using `fetch` and `htmx` instead of jQuery AJAX
