fix(web): Added missing type data for "module.hot" calls (#1500)

## Problem

- RPM build [fails with this
error](https://build.opensuse.org/package/live_build_log/systemsmanagement:Agama:Devel/agama-web-ui/openSUSE_Tumbleweed/x86_64):
  ```
  ERROR in /home/abuild/rpmbuild/BUILD/agama/src/context/installer.jsx
  ./src/context/installer.jsx 93:15-18
[tsl] ERROR in
/home/abuild/rpmbuild/BUILD/agama/src/context/installer.jsx(93,16)
      TS2339: Property 'hot' does not exist on type 'NodeModule'.
  ```
- It fails because the `module.hot` is not known

## Solution

- Explicitly load the types from the `@types/webpack-env` package
- Suggested solution found [here](https://stackoverflow.com/a/68539136)

## Testing

- Tested manually, the package now builds with `osc build` locally
