[gatsby-plugin-emotion] old 3.x files published in 4.0.5 build

[wKovacs64]

#11482 has struck again.

Description

gatsby-plugin-emotion 4.0.5 is breaking builds where 4.0.4 succeeded. Some old files from 3.x (gatsby-browser.js, gatsby-ssr.js, and wrap-element.js) made it into the published package. These files were originally deleted in #10500.

Compare 4.0.4 to 4.0.5 on unpkg:

https://unpkg.com/gatsby-plugin-emotion@4.0.4/ (correct)
https://unpkg.com/gatsby-plugin-emotion@4.0.5/ (incorrect)

Steps to reproduce

N/A

Expected result

I would expect only the current files to be in the corresponding published package.

Actual result

Additional files (not in the current source tree) are being included in the published package.

Environment
