chore(NODE-6271): update dev deps and add dependabot config

[baileympearson]

Description

What is changing?

Updates dev deps and adds a dependabot config.

For the same reason as outlined in our FLE bindings, this PR doesn't update node-gyp and prebuild because our docker images don't have python3.10 installed, required for the new node-gyp version.

I did try and install python3.10 for a while in our dockerfile, but ran into issues. We're still on the current major version of node-gyp, we should be fine with this version for a while.

(see mongodb-js/mongodb-client-encryption#41)

Is there new documentation needed for these changes?

What is the motivation for this change?
