Add a list of sponsors and hosts

[lgrigoryeva1]

Add a list of (logos) sponsors and companies that have hosted our events.

These would be:

• Valohai
• Anders Innovations
• Identio
• Reaktor

We could actually add the logos to the (english) folders of the events with a naming pattern (eg. logo-host-nameOfTheHost), and then query them (and filter out duplicates) with something like:

query GetSponsorLogos {
  allFile(filter: {extension: {}, relativeDirectory: {regex: "/(en/)\\w+/g"}, name: {regex: "/(logo-host-)\\w+/g"}}) {
    edges {
      node {
        relativePath
        name
      }
    }
  }
}

And then just maybe get the name of the host with regex from the name-field.

Hey @mialav, how things are going with the issue? Is there anything we could do to help with it? 😊
