[monitor, theia] Consider not pulling in the `@theia/plugin-ext` dependency for the modal dialog

[kittaakos]

Is your feature request related to a problem? Please describe.

Depending on @eclipse-theiacloud/monitor-theia unnecessarily pulls the following dependencies into the Theia-base app:

"@theia/bulk-edit": "1.59.0",
"@theia/callhierarchy": "1.59.0",
"@theia/console": "1.59.0",
"@theia/core": "1.59.0",
"@theia/debug": "1.59.0",
"@theia/editor": "1.59.0",
"@theia/editor-preview": "1.59.0",
"@theia/file-search": "1.59.0",
"@theia/filesystem": "1.59.0",
"@theia/markers": "1.59.0",
"@theia/messages": "1.59.0",
"@theia/monaco": "1.59.0",
"@theia/monaco-editor-core": "1.96.302",
"@theia/navigator": "1.59.0",
"@theia/notebook": "1.59.0",
"@theia/output": "1.59.0",
"@theia/plugin": "1.59.0",
"@theia/preferences": "1.59.0",
"@theia/scm": "1.59.0",
"@theia/search-in-workspace": "1.59.0",
"@theia/task": "1.59.0",
"@theia/terminal": "1.59.0",
"@theia/test": "1.59.0",
"@theia/timeline": "1.59.0",
"@theia/typehierarchy": "1.59.0",
"@theia/variable-resolver": "1.59.0",
"@theia/workspace": "1.59.0",

Consider a bare-minimum application that wishes to monitor user activity to time out the session prematurely; now, all these dependencies 👆 are pulled into the app just for a modal dialog.

Describe the solution you'd like

@eclipse-theiacloud/monitor-theia does not pull in unnecessary dependencies or features.

Describe alternatives you've considered

Pipe dream: there is a modal dialog in @theia/core; @eclipse-theiacloud/monitor-theia depends on @theia/core.
