### Bug description

Hello,

I publish my blog with Quarto. I am getting error with generated XML RSS feed:

```
This page contains the following errors:
error on line 8 at column 30: xmlParseEntityRef: no name
Below is a rendering of the page up to the first error.
```

[Here](https://github.com/mrtkp9993/MyDsProjects/blob/main/docs/index.xml) is the generated XML feed. Error didn't change whether if I build with Rstudio or Quarto CLI.

Quarto version: 1.2.90
RStudio version: 2022.07.1 Build 554
OS: Win 10 Pro Version 10.0.19044 Build 19044
