Compatibility with polylang

Seems this plugin is not working well with some i18n plugins like polylang. Saving a tab with custom products overwrites the translated tab with the saved products.

So this plugin should either ignore syncing _wb_tab_products post meta (see also https://polylang.pro/documentation/support/developers/the-wpml-config-xml-file/) or change product IDs to translated product IDs using a polylang filter (https://polylang.pro/documentation/support/developers/filter-reference/#pll_copy_post_metas).

PS: I’m willing to create a patch, but haven’t found your plugin on github or somewhere else. Is your repository publicly available? If yes, can you may send me the url? 🙂
