in docs, pnpm approve-builds (#25839)

## Description

Two fixes:
1. in docs, pnpm approve-builds for "linkcheck-bin"
2. Work around bug in lint checker where it cannot handle the generated
link to itself for a markdown section `#### 🌶️ Spicy`. Removing the
`FE0F` ( `VARIATION SELECTOR-16` ) from 🌶️to work around bug (giving 🌶)
seems to fix it.
