deps: Bump gatsby bundler plugins to 2.20.1 to fix error

[julianCast]

Fixes https://github.com/getsentry/sentry-javascript/issues/13504

Due to a racing condition, the version used in package @sentry/webpack-plugin for gatsby is causing the parameter filesToDeleteAfterUpload not working properly because the maps are being deleted before being uploaded to the server.

This bumps the dependency to the version it was fixed. Same version you guys already use in nextJs.

Before submitting a pull request, please take a look at our Contributing guidelines and verify:
