Nitter RSS: Handle over-processed links and metadata

[nemobis]

Using the RSS import option with Nitter works quite well, but the resulting posts are hard to read because every hashtag

Also, the nitter_base_url isn't applied because the links to the original post go to the URL provided by the RSS feed rather than to the original.

An example RSS feed from an instance running 2023.05.30-38985af is:

<?xml version="1.0" encoding="UTF-8"?>
<rss xmlns:atom="http://www.w3.org/2005/Atom" xmlns:dc="http://purl.org/dc/elements/1.1/" version="2.0">

Also I'm not sure it's useful to prefix "RT by " rather than just "RT", as in https://respublicae.eu/@EURLex/110603985605674224:

RT by [@EURLex](https://respublicae.eu/@EURLex): .[@EUinNL](https://respublicae.eu/@EUinNL) [#tenders](https://respublicae.eu/tags/tenders) - Netherlands-The Hague: Security Guard and Reception/Switchboard Services for the Premises in the Netherlands - 17/07/2023 - https://europa.eu/!xcTcYg

Some of the issues were already reported at https://github.com/robertoszek/pleroma-bot/issues/122 and fixed in the test version, will need to check again.

The current state can be seen at https://respublicae.eu/@EURLex (using 1.1.1rc58).

The author field can be missing too

The above exception was the direct cause of the following exception:

Should probably also drop the HTML markup in posts like https://kolektiva.social/@pyorapajahelsinki/111443408564161235 (but this is from a Telegram feed: https://rsshub.app/telegram/channel/pyorapaja ).
