Implement an interactive getting started guide for the Web Editor

The tour related to OIDC login needs to be a bit more fine-grained. Especially, we would want to explain the Client ID field if it is shown.

@christophfriedrich is right with his comment though, so we need to find a solution later:

I can try whether I can detect whether there is OIDC auth on the current server or not, but at the moment I wouldn't know how to do this in Tour.vue 🤔 Is this info available via some this. variable?

Can you provide me with an explanation you would like to see for Client ID? I don't know too much about it myself...

The info is indirectly available by querying the DOM for whether the corresponding UI elements are there. Not the nicest way, but works.

openeo-web-editor/src/components/Tour.vue

Line 127 in 8e254f6

if (document.querySelector(this.entries['login-internal'].target) !== null) { // server has basic auth

which is

if (document.querySelector('#credentials > .tabsHeader > button[title=Internal]') !== null) {

Another way of doing this:

if (Array.from(document.getElementsByTagName('button')).some(e => e.title == 'Internal')) {

Open issue reported by @christophfriedrich:

The only issue I still encountered and can't really think of a way to fix: When a user is on the e.g. "Internal" tab, starts the tour, and then switches over to "No credentials", the tour crashes because the step for the input fields (login-credentials) was already loaded, but the target has since been removed from the DOM...

esa requests a tour for the data processing / batch job area.
