Establish a "Workspaces" section in user settings

MR: Pending

Description

Problem

For a couple of upcoming features and configuration options we will need to allow users to set their individual preferences for Remote Development workspaces:

• Timeout period
• Variables
• Editor (VS Code, JetBrains, ...)

We already enable users to set necessary configuration for Remote Development on the group level in a "Workspaces" section in the group settings:

Solution

Just like we already have on the Group settings level, we should have a "Workspaces" section in the User settings.

The initial setting used to drive this feature will be project_cloner_image, for users that may need to have custom control over how they clone their repos (there have already been some requests for this).

• See Related Issues and MRs section in that epic for related issues and MRs

Acceptance Criteria

• Add UserSettings step to the Workspaces Settings Module
• Add new section in User settings. Should behave similar to settings for Agent and Cascading Settings levels, which will be added as part of Workspaces Settings Configuration Infrastructur... (&14186)

Technical Requirements

Add UserSettings step to the Workspaces Settings Module:

• This will involve adding a new UserSettings step to the Workspaces ROP Settings Module chain
• This step will observed the locked flag for each relevant setting, just as we previously added for lib/remote_development/settings/current_settings_reader.rb.
