bootloader_settings does not support duplicate option names

[divialth]

The role currently cannot apply multiple values for the same kernel argument name in bootloader_settings.

This is a valid GRUB use case, for example setting both local and serial console output with two console= entries.

Reproducer
Use this role input:

bootloader_settings:
  - kernel: ALL
    options:
      - name: console
        value: tty0
      - name: console
        value: ttyS0

Run the role and inspect resulting kernel args via grubby --info=ALL.

Expected behavior
Both values should be present in kernel args, e.g.:

... console=tty0 console=ttyS0 ...

Actual behavior
Only one value is effectively configured (the last defined entry), so one console= is lost.

Why this matters
Multiple console= parameters are a common/valid Linux boot configuration (e.g. physical console + serial console).
Current behavior prevents expressing that desired state with the role.
