📝 Remove trailing backslashes from embed links

[JFWooten4]

There are a lot of links right now that unnecessarily end with a trailing / before the closing ).¹ These double punctuation marks create an unpleasant interruption in line edits and copy scans. For instance, ten API pages across two ymls say:

can be used tio track the payment in the Stellar network using Stellar Laboratory, or StellarExpert."

They go on to use JSON commas, strKeys in quotes, and curly brackets to encode documentation. If you look through that quickly and get distracted by all the fancy punctuation, you could easily miss the blatant "tio" typo in the middle of the sentence. Thus, we can simplify the review process by cleaning up these old, dirty formats so that new contributions can stand beautifully on their own.

Also, the terminal backslashes visually break up already messy markdown tables without additional spacing, like in docs/data/analytics/analytics-providers/analytics-providers.mdx. It's very hard to proofread these big text blobs already, and the extra symbols just make it even more difficult to identify pipes that are only space-delineated. By simplifying the imports in the embeds, it should be a lot easier to clearly improve graphed chart data going forward.

I accidentally put de3c970 and 3f0f080 images on this branch. They were migrated to a proper diagram PR in #2400. It looks like the relevant commits were taken into #2409, and we can leave that as the merge for this principal fix.

Closing in favor of Bri's version, which maintains proper scope and removes unnecessary i18n Spanish changes.
