docs: add Polish translation of Biome README

[SzymCode]

Summary

This PR introduces the Polish translation of the Biome documentation.
The motivation is to increase the accessibility of Biome for Polish developers and to expand the open-source community around the project. (Maybe this will also speed up full SFC support for Vue 😃)

Adding a Polish version will:

• help Polish developers who are more comfortable reading in their native language,
• lower the barrier of entry for new contributors from Poland,
• increase Biome’s visibility in the Polish programming community.

This idea was also discussed on Discord, and several community members reacted positively to the proposal.

Please don't merge until I finish 😅

Walkthrough

Adds a Polish translation file packages/@biomejs/biome/README.pl.md and inserts a “Polski” entry linking to it across multiple localized README files (including README.md). The Polish README provides badges, language navigation, install/usage instructions, documentation/playground links and a sponsors section. No source code, exports or public API were changed.

32-32: Navigation entry looks spot on.

Polski slot is added cleanly and keeps the language list tidy. All good from my side.
