Output file must end with ".svg", ".png" or ".pdf"

Describe the bug I installed the mmdc v8.11.0 from homebrew using brew install mermaid-cli as described in documentation and run mmdc -i documentation.template.md -o documentation.md where documentation.template.md contains mermaid snippets in markdown file. Then, instead of getting transformed MD, I got the error Output file must end with ".svg", ".png" or ".pdf".

To Reproduce Steps to reproduce the behavior:

1. Install latest mermaid-cli from Homebrew with brew install mermaid-cli
2. Create a markdown file with mermaid blocks
3. execute mmdc -i yourfile.md -o destination.md
4. See the error

Expected behavior Instead of error, a transformed markdown file should appear.

We are on release 9.0.3. Please, check if the error is fixed there.

But even if I install from NPM with npm install -g mermaid, I still don’t get the version 9.0.3.

The version from npm, strangely, reports 0.2.4. What did I do wrong?

EDIT: OK, I needed to run npm install -g @mermaid-js/mermaid-cli. 😊 Then it works correctly.
