Standard summary and old blog posts contain invalid link to calendly

[pietrushnic]

We decided to cancel the Calendly subscription and migrate to our appointment scheduling solution based on Nextcloud. Unfortunately, blog post summaries still link to the old scheduling page, which potentially may lead to losing customers. We know customers use links from summary because we receive feedback it does not work.

What links should be used:

• Dasharo Products Discovery Call
• Initial Consultation for generic inquiries
• Pace Enterprise Training Introductory Call
• Zarhus Products Introductory Call

All links should be fixed.
