Update sites.yml - added brunofontes.net

[brunofontes]

Added https://brunofontes.net to the list
https://gtmetrix.com/reports/brunofontes.net/9TrlTWSV/

This PR is:

• Adding a new domain
• Updating existing domain size
• Changing domain name
• Removing existing domain from list
• Website code changes (512kb.club site)
• Other not listed

• I used the uncompressed size of the site
• I have included a link to the GTMetrix report
• This site is not an ultra lightweight site
• The following information is filled identical to the data file

I confirm that I have read the FAQ section, particularly the two red items around minimal pages and inappropriate content and I attest that this site is neither of these things.

• Check to confirm

- domain: brunofontes.net
  url: https://brunofontes.net/
  size: 271
  last_checked: 2023-11-12
