fix: panic when starting with dashboard v2

[fuyufjh]

What's changed and what's your intention?

If you start risingwave playground via cargo run --bin risingwave -- playground with enable-dashboard-v2: true, it will panic and complain "environment variable not found". This PR fixes this.

That's weird. The env variable is configured in risedevtool/common.toml 🤣

Yes, there's no problem if starting with risedev p, but

cargo run --bin risingwave -- playground

will fail. Any better solution?

In this case, I think it's okay to get this PR merged.
