source-highlight: correct reference to lesspipe.sh
https://github.com/void-linux/void-packages/pull/22088

Description:
The script `src-hilite-lesspipe.sh` installed by `source-highlight` excpects to find an executable named `lesspipe` as a helper. The `lesspipe` package installs this helper as `lesspipe.sh`, so the `source-highlight` template has been modified to replace the `lesspipe` invocation with `lesspipe.sh`.
