Add optional depth parameter to envd's ListDir

[0div]

Description

This envd change allows us to add an optional depth parameter to files.list method on the SDK.

The DX on the SDK side would look like this:

const files = await sandbox.files.list(dirName, { depth: 3 })

• update pb spec
• generate pb go files
• update ListDir method

Test

• infra integration test
• SDK tests

I think this looks good to me, but keep in mind that "filepath.WalkDir reads an entire directory into memory before proceeding to walk that directory"

oh wow really ? where did you see this?

I think this looks good to me, but keep in mind that "filepath.WalkDir reads an entire directory into memory before proceeding to walk that directory"

it reads stores names of the files / directories, which should be fine

@mishushakov Can you merge if everything looks ok to you from both technical and DX perspective?
Then please finalize e2b-dev/E2B#649 and coordinate releasing of SDKs with the deployment of the envd change.

Looks good, minor nits

Make tests explicit and the rest looks good
