Fix missing Slack lodash, async-retry dependencies (#16375)

This commit updates the `@pipedream/slack` package to include missing
dependencies.

The `lodash` and `async-retry` packages were imported in
`components/slack/slack.app.mjs` but not included as dependencies in
`components/slack/package.json`.
