We want Zstandard compression to be available across the board, as
it's generally better than gzip with lower memory requirements.

Pretty sure you don't need to set CONFIG_ZSTD_COMPRESS as it's selected by
CONFIG_CRYPTO_ZSTD:

config CRYPTO_ZSTD
        tristate "Zstd compression algorithm"
        select CRYPTO_ALGAPI
        select CRYPTO_ACOMP2
        select ZSTD_COMPRESS
        select ZSTD_DECOMPRESS
```

Because the 'Limited CI::created' was not defined in our labels.yaml so the
event that caused it to need to be applied was held in a retry queue. In the
meantime, the CI passed and the event to add the defined 'Limited CI::OK'
label was processed without issue. Then when the 'created' issue was fixed
that event was finally processed and here we are.

this patch should not only provide `common/generic/CONFIG_CRYPTO_ZSTD` but
also remove `ark/generic/CONFIG_CRYPTO_ZSTD`. otherwise the latter overrides
the former. could you please update the patch?

i would suggest brushing this up a bit more in a form of the 2nd patch: move
all `redhat/configs/fedora/generic/CONFIG_ZRAM_DEF_*` to
`redhat/configs/common/generic/` (with overwrites) so both distributions share
the same set of sane zram configs.

currently a number of zram configs are not covered in ark. namely,
`redhat/configs/ark/generic/CONFIG_ZRAM_DEF_COMP_LZ4HC` and 2 others are
missing.

`redhat/configs/common/generic/CONFIG_ZRAM_DEF_COMP_ZSTD` should be `#
CONFIG_ZRAM_DEF_COMP_ZSTD is not set`, not `=n`. just move `fedora/` version
of this file to `common/`.
