Link formatting issue in message popup

Found a minor bug related to the rust-analyzer popup showing when a project doesn't have a Cargo.toml file. See the screenshot below:

It looks like the message is expected to be rendered as Markdown (the linkedProjects link) but it's showing as plain text instead.

rust-analyzer version: (eg. output of "rust-analyzer: Show RA Version" command, accessible in VSCode via Ctrl/⌘+Shift+P)
rust-analyzer version: 0.3.1958-standalone (5bf2f85c8 2024-05-09)

rustc version: (eg. output of rustc -V)
rustc 1.77.2 (25ef9e3d8 2024-04-09)

editor or extension: (eg. VSCode, Vim, Emacs, etc. For VSCode users, specify your extension version; for users of other editors, provide the distribution if applicable)
VS Code

relevant settings: (eg. client settings, or environment variables like CARGO, RUSTC, RUSTUP_HOME or CARGO_HOME)

repository link (if public, optional): (eg. rust-analyzer)

code snippet to reproduce:

// add your code here

Reproduce the VS Code rust-analyzer popup in a project without a Cargo.toml file and trace how the linkedProjects message is rendered. Check the popup's Markdown handling and verify that the link is displayed as a clickable Markdown link rather than plain text.
