Upgrade mermaid-rs-renderer to get emoji font fallback in SVG

[llimllib]

Summary

Upgrade to the next release of mermaid-rs-renderer (after v0.2.2) to get emoji font fallback support at the SVG generation level.

Background

mermaid-rs-renderer added emoji font families to the default SVG font-family attributes in commit ec47de0:

font_family: "'trebuchet ms', verdana, arial, \"Noto Color Emoji\", \"Apple Color Emoji\", \"Segoe UI Emoji\", sans-serif"

This is currently 8 commits after v0.2.2 and not yet in a release.

Benefits

Once we upgrade, we'll have defense in depth for emoji rendering:

1. SVG level (from mermaid-rs-renderer): The generated SVG explicitly requests emoji fonts as fallbacks
2. Rasterization level (our fix in Fix emoji rendering in SVG rasterization #66): fontdb pre-loading ensures emoji fonts are available and .LastResort doesn't interfere

These complement each other rather than conflict. The SVG font-family list makes the intent explicit, while our fontdb ordering ensures it actually works during rasterization.

Action Required

When mermaid-rs-renderer releases their next version (likely v0.2.3 or v0.3.0):

# In Cargo.toml
mermaid-rs-renderer = { version = "0.2.3", default-features = false }

Then run:

cargo update
cargo build
cargo test

No code changes required - just a version bump.
