Out of date error

A couple of problems have been introduced due to a lack of sync between our English JSON files in dev and the JSON files we've pulled from CrowdIn. This is causing several pages to mistakenly label pages that are out-of-date. Documenting here but worth noting this is probably happening on all of the updates we uploaded yesterday.

Current pages that are showing as out-of-date that shouldn't be are:

1. /wallets/find-wallet/
   -- Caused by having page-find-wallet-yet reintroduced in page-wallets-find-wallet.json. I've removed it and merged the text from it to page-find-wallet-not-all-features

2. /eth2/
   -- Caused by re-adding eth2-client-trinity-logo-alt back into page-eth2-index.json. I have removed it (Trinity client is deprecated and we don't list it anymore here)

3. /eth2/vision/
   -- Caused by re-adding page-eth2-vision-The. I've deleted this. We don't need to add anything as this is not used (confirmed by searching an old branch from August that this hasn't been used in /eth2/vision.js for a while.

4. /eth2/merge/
   -- I think this might be caused by deleting the comment that has a heading in it? (We now check the number of headings in markdown files I believe?) I've re-introduced this temporarily to test this assumption.

5. /eth2/bug-bounty/
   -- Caused by reintroducing page-eth2-bug-bounty-quality-fix-desc in page-eth2-get-involved-bug-bounty.json. I've removed this and merged the content into page-eth2-bug-bounty-quality-fix
   -- Note: this makes the third list item here lose its description

Programmatic text in strings

Not a new issue but noticed more than a few occurrences of translators trying to add programmatic things in text (i.e. \nwerden sämtliche Prämien für auf or hinzugefügt wird, \"zusammengeführt\".

Didn't want to spend too long on this but we should probably do a sweep of the codebase for this after we merge all the new language content.

---

Merge / Sharding dates

Merge/sharding dates have been knocked back to the previous version for this. Again, we should do a sweep after merging.

All issues fixed except find-wallets is still showing as out of date. Maybe we added new wallets?
