Subject: [PATCH] fix: replace apostrophe with empty string in header
 slugification (#1618)

* Replace apostrophe with empty string in header

This change is to replicate the github behviour with respect to apostrophe in
headers. When there is an apostrophe in a header, github replaces it with empty string
when creating an anchor link to that header. Docusaurus should follow the same convention.
