Cannot build examples/rust-basic

[NewGyu]

Sorry for the boring point, when running cargo build, the errors below was occurred.

$ cargo build --target wasm32-wasi --release
   Compiling rust-basic v0.1.0 (/workspaces/wasm-workers-server/examples/rust-basic)
error: invalid format string: expected `'}'`, found `'m'`
  --> src/main.rs:19:16

19 |         body { max-width: 1000px; }
   |              - ^ expected `}` in format string
   |              |
   |              because of this opening brace
   |
   = note: if you intended to print `{`, you can escape it using `{{`

I think { and } should be replaced to {{ and }}.

    <style>
        body {{ max-width: 1000px; }}
        main {{ margin: 5rem 0; }}
        h1, p {{ text-align: center; }}
        h1 {{ margin-bottom: 2rem; }}
        pre {{ font-size: .9rem; }}
        pre > code {{ padding: 2rem; }}
        p {{ margin-top: 2rem; }}
    </style>

Thank you.
