* fix(site): escape flags with backticks
In the generated markdown docs, flags like `--foo` inside
help texts currently get pretty-printed as `–foo` with an em-dash.
This change applies backticks via a regex replacement, so that
they appear as `--foo` in the docs but remain as --foo in the
CLI output.
