Improve trust in testimonials by adding source links

[vitormattos]

Some testimonials on the LibreSign website come from public reviews on other websites.

Today, we show the review text and the username, but we do not show where the review came from. This can make some testimonials look less trustworthy, especially when the username looks unusual, such as 0-bandage-dugouts.

For example, this testimonial comes from AlternativeTo:

https://alternativeto.net/software/libresign/about/#post-142731

We should make the source of testimonials clear and give visitors a way to check the original review.

Suggested changes

• Add a link to the original review when possible.
• Show the name of the source website, for example, AlternativeTo.
• Check how unusual usernames are shown on the website.
• Keep the original meaning of the testimonial.
• Use the same format for all testimonials on the website.
• Use an array to add the Testimonials creating a pattern with all parameters that is necessary to render the testimonials card, by example:
  • Author (optional to solve the current issue )
  • Description
  • Origin
  • URL

The goal is to make the testimonials clearer and more trustworthy.

Hi! I'd like to work on this. I'll refactor the testimonials into a consistent data structure and add source/origin links where available.
