Add breadcrumbs back + fix meaningfull URLs + add developpers instructions

[benoit74]

Would solve #66 and #64 and #31 once merged to main, but not yet ready to be merged in this branch (other issues have to be fixed)

Changes:

• removed outdated release instructions (we now have a Github task issue)
• developer instructions for local Vue.JS debugging
• add breadcrumbs back
• slug value is always computed where requesting a node to database
  • slug is populated in node, its parents and children
  • this has the side effect that node parents and children are not generators anymore
• final computation of node slug as agreed on issue URLs should be meaningful #31
  • in case of slug conflict for two nodes, scraper stops

Thank you ;

Have you had the chance to run it on a large channel like Khan ?

Nope ... Is there a language which would make more sense? en/es/fr?

[rgaudin]

I'd say FR because it's large and easier for you to spot issues when browsing

I just started Khan Academy FR on my machine, it will probably run for many days so I propose to move forward this PR without waiting for the result, we are not yet at the point of merging this to main anyway.

@rgaudin I assume it means I can resolve the conversation and merge the PR
