[improvement/integration-action-expansion] Gmail integration cannot download attachments

[makiroll1125]

What happened:
CraftBot was unable to download attachments from an email in Gmail

What I expected:
CraftBot should be able to search for attachments in an email and download them to the user's Google drive or the agent workspace

Steps to reproduce:

1. Open CraftBot and connect to Gmail integration
2. Find an email with a downloadable attachment
3. Ask CraftBot to download the attachment in that email

Environment: (browser, OS, server, version/commit)
Browser: Microsoft Edge
OS: Windows 11
Branch: improvement/integration-action-expansion (PR #271)
