BIP-372: Fix references and links formatting and minor typos

[mutestt]

Fixed incorrect preposition in key tweaking explanation:

• multiplied on → multiplied by

• Clarified BIP-340 key serialization:

  • appending '02' → appending '0x02'

• Removed unnecessary trailing comma in the list of output types

• Removed erroneous semicolon after URL

Thank you for your proposal. We usually no longer merge "fix typos and grammar" PRs directly, as we were seeing a high frequency of them, they can require more time than they are worth, and they create unneeded notifications for subscribers to this repository. We instead batch these kinds of changes into an occasional cleanup by the editors and credit you as an author when we do that.

That said, I think this pull could add value beyond "typo fixes" if you update it to also convert the non-functional links to mediawiki format. Thoughts?

@jonatack
I’ve updated the PR as suggested: all non-functional and raw URLs in the references section have now been converted to proper MediaWiki format.
Please let me know if anything else needs to be adjusted.

Looks good, modulo why did you add italics, and then remove them again in the last commit ce19ffa? (No strong opinion but does seem more readable with italics.)

@jonatack
I’ve restored the italics around the reference titles as suggested. Let me know if there’s anything else you'd like adjusted.
