Docs: Documentation for Fresco plugin references old maven location

[rjmcleod-tw]

It looks like after 0.182.0, flipper-fresco-plugin started sharing a version with Fresco and moved from com.facebook.flipper to com.facebook.fresco, but the documentation for the fresco plugin still references the old location. Since the newest version of the plugin at com.facebook.flipper does not work with the newest version of Fresco, trying to set things up according to the documentation will fail with this error:

e: Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
    class com.facebook.flipper.plugins.fresco.FrescoFlipperPlugin, unresolved supertypes: com.facebook.drawee.backends.pipeline.info.ImagePerfDataListener

There should also likely be an explicit note about the move for people like me who are upgrading from Fresco 2.6.0 and might end up pulling out what little is left of their hair trying to figure out why seemingly the latest version of the Fresco Flipper plugin doesn't compile with seemingly the latest version of Fresco.

If you came here from a web search, what you want is this (replacing 3.2.0 with whatever version of Fresco you're using):
debugImplementation 'com.facebook.fresco:flipper-fresco-plugin:3.2.0
