Move SGLang to ToT in Dockerfile.gb200

[kyleliang-nv]

Motivation

Dockerfile.gb200 currently contains a work-around for flashinfer, due to the missing arm package for 0.2.9rc1.
The problem have since been resolved in flashinfer 0.2.9rc2.
Hence, the work-around is no longer needed.

Modifications

Install ToT Sglang inside Dockerfile.gb200 instead of sglang with flashinfer 0.2.7.post1

Accuracy Test

Benchmark & Profiling

Tested this PR by building/publishing the docker image built with Dockerfile.gb200 onto dockerhub,
verified no performance or health issue regarding running SGLang on GB200.

Summary of Changes

Hello @kyleliang-nv, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request updates the Dockerfile.gb200 to utilize the most current version of SGLang, removing a specific version pin that was previously required due to a dependency workaround. This change also introduces a minor optimization to the Docker build process.

Highlights

• SGLang Version Update: The Dockerfile.gb200 has been updated to fetch the latest 'Tip of Tree' (ToT) version of SGLang directly from its Git repository. This removes a previously pinned commit (a167fd0bcb9ef4b0f4331a109e40c8cdc770b026), as the underlying flashinfer issue that necessitated the workaround has been resolved.
• Docker Build Optimization: The git clone command for SGLang now includes the --depth=1 flag. This optimizes the Docker image build process by performing a shallow clone, fetching only the latest commit and reducing the overall download size and time.
