Rename file + default export in one command

[franciscolourenco]

Is your feature request related to a problem? Please describe.
In JS/TS codebases, it is common for files to default export a function with the same name as the file. In those cases, when renaming a file, it is also necessary to rename the function.

Describe the solution you'd like
I would like a command that renames both the file and the default export at the same time.
