Add "Git Services" tab to the User Preferences

[ibuziuk]

Is your task related to a problem? Please describe

Currently, the account page is outdated and fetches the user information from db that is planned to be removed as part of #21374

The data provided on the Account page is irrelevant and should be removed

Describe the solution you'd like

As part of this issue, we should only have the login / logout buttons to the main Git providers GitHub, Gitlab, and Bitbucketlogin/logout

Sub-tasks

• remove dependecy on /user and /profile API (display only username from k8s as the first step)
  • hide 'Account' view
• [ ]

Describe alternatives you've considered

Potentially we should remove Account page completely and add Git Services Tab to the User Preferences:

Additional context

The information about the configuration of the particular Git provider should be fetched from the Eclipse Che CR - #21577

The issue is part of the Git Zero Config epic - #20583

Open Questions:

• login / logout URLs should be provided by the Che CR
• how should we track the login / logout state for a particular user

Release Notes Text

Eclipse Che User Preferences page includes a new tab: "Git Services" (before, the only tab was "Container Registries"). This tab shows the list of git services the user has granted access to. User can revoke access to any of the git services from this tab. Supported services are GitHub (github.com or Enterprise), GitLab (SaaS and Server) or Bitbucket (Cloud and Server).

As the first step, it would be great to remove the dependency on the server /user API

@l0rd @akurinnoy @olexii4 please, find the proposed UX for Git Services

Basically, the idea is that a particular icon is shown only if the admin configured the git service on the CR level accordingly - #21577

The only possible options would be login / logout from the dropdown

[ibuziuk]

after discussion with @l0rd for Git Services Tab we want to have the very same UX as we currently have for the "Container Registries"

Important notes:

• for the first iteration it should not be possible to add a 'Git Service' from UD
• UD shows a 'Git Service' in the table based on the git-credential-secret from the user namespace
• When a user deletes a 'Git Service' the corresponding secret is removed from the namespace and the access from the OAuth app is revoked

[l0rd]

When implementing this we should address the bug described in this Dev Spaces issue too.
