fix(vscode): Add base path for svgs and remove duplicated code

[ccastrotrejo]

This pull request primarily focuses on streamlining the codebase in two files: openMonitoringViewBase.ts and vite.config.ts. The most significant changes include the removal of a method in the OpenMonitoringViewBase class and an adjustment to the configuration in vite.config.ts.

• The getPanelOptions method was removed from the OpenMonitoringViewBase class. This method previously returned webview options for the panel. Its removal suggests that the default options are now being used or they're being defined elsewhere.
• The configuration for Vite, a build tool used in the project, was modified. The base option was added and set to './', which changes the base public path when serving or building the project.
