Accessibility for the webpage

[sxd]

During the evaluation of the OpenSSF best practices I find out that our site has some issue with accessibility using the following link https://wave.webaim.org/report#/https://cloudnative-pg.io we should try to address this issue, since this could affect a lot of people.

Hi @sxd,
I'd like to work on fixing the accessibility issues identified in this issue.
I plan to:

1. Run the WAVE accessibility evaluation on cloudnative-pg.io to identify all specific issues
2. Fix common accessibility problems including:
   • Missing alt text on images
   • Color contrast issues
   • Form label associations
   • Heading hierarchy
   • Any other issues found in the WAVE report
3. Update the Hugo templates and CSS as needed
4. Test the changes locally before submitting a PR
   I'd be happy to take ownership and submit a pull request with the fixes.
   Thanks!

Hi @sxd @gbartolini @FloorD I was working on this since yesterday and have made significant progress. I am currently working on it and will further increase the score but three points. Just some contrast issues remain.

Please review the linked PR
