should have docs how to upgrade teracy-dev from v0.5 to v0.6

[hoatle]

for example, by using https://github.com/teracyhq-incubator/teracy-dev-entry-v05 or users should create their own teracy-dev-entry repo if needed (which includes https://github.com/teracyhq-incubator/teracy-dev-essential and https://github.com/teracyhq-incubator/teracy-dev-v05-compat) and migration experience to write docs

take projects from https://github.com/acme101/ for example instruction:

• https://github.com/acme101/dev-setup
• https://github.com/acme101/ror-starter/tree/develop
• https://github.com/acme101/nextjs-hello-world
