Miscellaneous fixes to the contents of the articles

Hi👋 Highly insightful website on guides to digital safety! A big thanks for the great work done on this website. While reading along, I noticed a couple of minor issues. Here's a PR with my proposed changes.

Changes

1. "attack vetor" -> "attack vector"
2. "...cars Pearson..." -> "...cars. Pearson"
3. Added closing **s where they were missing in metadata.mdx & backups.mdx .

Converted to draft because I noticed a potential typo in another page. I'll make the PR ready for review after I complete my reading of the entire website.

Sorry it's taken me so long to reply to this. I appreciate you finding these errors! Definitely just let me know when you're ready and I'll review it.

Sorry it's taken me so long to reply to this.

No worries!

Also, could you please have a look at my previous two commits and check whether they're what you intended. For some reason there were two asterisks that were escaped using \. I didn't realise that to bold-en in .mdx the same syntax as standard markdown is used.

The same case for a0a0648

Alright, the PR is ready for review. I haven't completed reading the entire website yet due to limitations I face currently, so this is all I have for now.

I suck at using GitHub correctly. They all look right except for the Cryptomator one, that whole sentence should be bold and not just the one. I'll fix it after merging.
