Improve FAQ block with meaningful IDs & auto-expansion of answers

[robyngit]

Currently, each FAQ item is assigned an id based on its order in the accordion (e.g., #acc_1-3). This makes linking to specific FAQs brittle and unclear. To improve this, we should make the IDs either:

• Based on the question text (e.g., #what-is-dataone)
• Or configurable via front matter so editors can assign custom IDs

When navigating to a specific FAQ URL with an anchor, the accordion should automatically expand that item.

This will make it easier to link to specific questions for support and documentation purposes.

ids based on the question text may get fairly long, for example:

what-if-i-dont-want-a-hosted-repository-but-still-want-to-use-dataone-to-store-my-data

On the other hand, it could become tedious to maintain a long list of shorter custom ids. I think I lean toward the former option, but the latter would have nicer links.
