scaffold taxonomy docs have incorrect rendering

[benlk]

On https://developer.wordpress.org/cli/commands/scaffold/taxonomy/, the docs display < and > instead of the respective glyphs:

--theme and --plugin should probably have identical formatting with regards to whether the =<name> is included inside the square brackets.

Note that the source code files here don't have those as HTML entities; this looks like a bug with the renderer, not the plugin's docs.

	* [--theme]
	* : Create a file in the active theme directory, instead of sending to
	* STDOUT. Specify a theme with `--theme=<theme>` to have the file placed in that theme.
