Styling in the documentation looks broken

[deshetti]

As mentioned in the title the styling in the documentation site is broken is not very easy to read the articles. https://go-colly.org/docs/introduction/start/

I looked up at the archived site and it seemed fine back then: https://web.archive.org/web/20221004034337/https://go-colly.org/docs/introduction/start/

I believe this is the cause of the issue:

 Mixed Content: The page at 'https://go-colly.org/docs/examples/basic/' was loaded over HTTPS,
 but requested an insecure stylesheet 'http://go-colly.org/css/semantic.min.css'.
 This request has been blocked; the content must be served over HTTPS.

Looked in Stack Overflow for a related issue, probably related to new browser rules: https://stackoverflow.com/questions/67765238/mixed-content-the-page-at-was-loaded-over-https-but-requested-an-insecure-resour
