[docs-only] docs: first draft of the custom apps in ocis and web blog post, part-1

it contains a good start for part 1, it needs some better writing here and there, should be enough as a starting point.

toDos:

• part-1: app basics, what it is, why you need it
  • basic article
  • text correction and better wording
• part-2: write and ship a basic custom extension
  • basic article
  • text correction and better wording
  • docker app dev example and sandbox
• part-3: advanced techniques and web-app sdk deep dive
  • basic article
  • text correction and better wording

@tbsbdr lets discuss the next steps

Thanks for opening this pull request! The maintainers of this repository would appreciate it if you would create a changelog item based on your changes.

The example is outdated!!
Why not re-using the new one which is refactored and is on the latest stage?
You could create a hello example based on ocis_full which would make imho much more sense.

@phil-davis I guess that a language review may be beneficial 😄

[phil-davis]

English looks good. Looking forward to future parts that will give lots more detail about making web apps.

[fschade]

@mmattel many thanks for the text tunings, applied!
