Summary: Mermaid XY Charts are vulnerable to an infinite loop DoS

Details: ### Impact Mermaid XY Charts are vulnerable to an infinite loop DoS attack in the `setXAxisRangeData()`, when configuring an X-Axis with invalid parameters. As each loop appends an element to an array, this would generally only cause an `RangeError: Invalid array length` to appear after a few seconds, but may cause the page/JavaScript process to crash due to memory exhaustion, depending on the environment. #### Proof-of-concept ```txt xychart x-axis 1 --> 1 line [1, 2] ``` ### Patches This has been patched in https://github.com/mermaid-js/mermaid/commit/630aa7e5dd417e1f56bff2a1ce8df2c5ad08d289 and released in [Mermaid v11.16.1](https://github.com/mermaid-js/mermaid/releases/tag/mermaid%4011.16.1).
