[PATCH v2 0/5] docs: pt_BR: Complete PGP maintainer guide translation

[Daniel Pereira <danielmaraboo@gmail.com>]

This series provides the complete Brazilian Portuguese translation for
the Kernel Maintainer PGP guide. The translation was divided into 
subsequent patches to facilitate review, covering PGP basics, hardware
tokens (smartcards), Git integration, and identity verification.

All internal cross-references were updated to ensure a clean Sphinx 
build, and terminology aligns with the existing pt_BR documentation.

Changes in v2:
- Fixed translation of "Periodic release snapshots" to "Arquivos 
  tarballs por release" as suggested by Mauro Carvalho Chehab.
- Corrected a double-hyphen formatting error in the first translation 
  patch.
- Added missing Signed-off-by and fixed line wrapping in the 
  KVM index patch (1/5).
- Rebased onto the latest docs-next branch.
