Missing favicons for some href's

[thilles]

As discussed in https://discord.com/channels/1130383047699738754/1261068436419776644

Some hrefs found are not a relative link to a favicon.ico image, but instead a full url to a static asset, resulting in missing favicons in the twenty-favicon cache. https://favicon.twenty.com/<companydomain>.

Another missing favicon is where the href is a relative link to a .svg file.

I believe the href pushed here has to be santized somewhat. https://github.com/twentyhq/favicon/blob/81024b6f5da85a7a1b5ec8057c2fa0908953d553/src/favicon/url-fetcher/html.url-fetcher.ts#L42

See example domains nnd.no, unibuss.no and lovenskiold.no
