Fixed #36537 -- Ensured unique HTML IDs for geometry widget option scripts in the admin.

Browse Source 
This work amends the code from f2f6046c0f92ff1faed057da0711ac478eef439c
where multiple geometry widgets rendered `<script>` elements in the
admin with the same HTML `id`, resulting in invalid HTML and fragile
JavaScript selectors. Refs #25706.

This change uses the widget's textarea ID to generate a unique `id` for
each JSON options `<script>`, ensuring valid and robust markup.
