Update devcontainer with chromium dependencies

When attempting to `npm install && npm run test` in a fresh codespace, we initially see an error related to a missing shared library:
```
26 04 2022 14:32:23.081:ERROR [launcher]: Cannot start ChromeHeadless
/workspaces/paste-markdown/node_modules/chromium/lib/chromium/chrome-linux/chrome: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory
```

Running
```
ldd /workspaces/paste-markdown/node_modules/chromium/lib/chromium/chrome-linux/chrome | grep not
```
shows a list of libraries similar to that in https://github.com/dtolstyi/node-chromium/issues/52#issuecomment-1028727251

```
libnss3.so => not found
libnssutil3.so => not found
libsmime3.so => not found
libnspr4.so => not found
libatk-1.0.so.0 => not found
libatk-bridge-2.0.so.0 => not found

libpango-1.0.so.0 => not found
libcairo.so.2 => not found

```
^^ This correlates pretty well to https://github.com/puppeteer/puppeteer/blob/main/docs/troubleshooting.md#chrome-headless-doesnt-launch-on-unix

Inspect the repository's devcontainer configuration and reproduce the failure with `npm install && npm run test` in a fresh Codespace. Use `ldd` on the Chromium binary to verify the missing libraries listed in the issue. Done means ChromeHeadless starts successfully and the test command no longer reports missing shared libraries.
