fix(coverage): use directory instead of files glob for Codecov upload (#2964)

The codecov CLI does not expand ** globs in the --file argument,
causing all uploads to find 0 coverage files. Switch to directory
scoped to plugins/ to let the action search recursively while still
excluding example apps (packages/app, packages/backend).
