[Security] Resolve Vulnerabilities - Attempt 2 (#88)

Resolves security vulnerabilities:
https://github.com/BitteProtocol/make-agent/security/dependabot

The previous attempt #65 did nothing. I kept digging and found this
solution works (at least locally)

## Test Plan

```sh
pnpm i && pnpm audit
```


Before removing localtunnel, the audit report with just the overrides
showed `axios` (`>=0.8.1 <0.28.0`).

So then

```
$ pnpm why axios
Legend: production dependency, optional only, dev only

dependencies:
localtunnel 2.0.2
└── axios 0.21.4
```
Removing local tunnel (no longer used) removed these issues!
