chore: add Gemini CLI install to devfile

[olexii4]

What does this PR do?

Adds Google Gemini CLI support to the devfile.yaml used for developing che-dashboard in a Che/DevSpaces workspace.

Two new entries are added:

• install-gemini-cli command — runs npm install -g @google/gemini-cli, exposed as a run-group command so it is directly accessible from the IDE command palette.
• run-gemini command — runs npx @google/gemini-cli, exposed as a run-group command so it is directly accessible from the IDE command palette.

  - id: install-gemini-cli
    exec:
      label: "[UD] install Gemini CLI"
      component: tools
      workingDir: ${PROJECT_SOURCE}
      commandLine: "npm install -g @google/gemini-cli"
  - id: run-gemini
    exec:
      label: "[UD] run Gemini"
      component: tools
      workingDir: ${PROJECT_SOURCE}
      commandLine: "npx @google/gemini-cli"
      group:
        kind: run

Screenshot/screencast of this PR

What issues does this PR fix or reference?

Is it tested? How?

1. Deploy Eclipse Che.
2. Open the Create Workspace page and select Import from Git.
3. Paste the following URL and create a new workspace:
   https://github.com/eclipse-che/che-dashboard/tree/update_devfile
4. Wait for the workspace to start — the postStart event runs npm install -g @google/gemini-cli automatically inside the tools container.
5. Once the workspace is ready, open the IDE command palette and run the [UD] install Gemini CLI, then [UD] run Gemini commands to confirm the CLI is available and functional.

It's not recommended to install apps, dependencies and other packages using the postStart hook.

Users should make their hook handlers as lightweight as possible.

@akurinnoy I have fixed it.
