Replace React Helment with Gatsby Head

[maxcell]

Summary

There was a warning within the console that recommended we use the built-in Gatsby head component as of Gatsby v4.19.0. This should reduce the amount of third-party dependencies we need. For the most part it also seems like it will reduce the amount of direct package size as well.

Documentation for Gatsby Head

Warning produced from the run command:

warn gatsby-plugin-react-helmet: Gatsby now has built-in support for modyfing
the document head. Learn more at https://gatsby.dev/gatsby-head

I saw this as well. Would it be just replacing the react-helmet component with gatsby-head?
