fix(docker): add deps for @vscode/sqlite3

The change to using @vscode/sqlite3 broke our deployment builds.
Adding the required build tool `g++` and linking `python` to the python3 executable.

```shell
make: Entering directory '/builds/.../node_modules/@vscode/sqlite3/build'
  ACTION deps_sqlite3_gyp_action_before_build_target_unpack_sqlite_dep Release/obj/gen/sqlite-autoconf-3360000/sqlite3.c
/bin/sh: python: not found
```

Technically, the python path can be added to `.nmprc`, but added it to the docker file instead.
