[debasishbsws]

This require handling it differently even though the ABI check pass. there is a ABI diffrence in this version and result in fail of downstream packages.

Please correct me if anything below is wrong:

Bumping all the things in a single PR does not guarantee that the new icu will be used to compile these dependants.

One most likely needs to land this separately - as in land icu in one PR into main; wait for it to build and publish; then land pr(s) with lots of wolfictl bumps. However such PRs will not do testing of this.

To pre-test such rebuilds, you can use staging to do rebuild with the icu rebuild draft PR. But there is another option with pure github:

• open icu pr (1), keep it draft wait for it to build
• open a new pr with wolfictl bumps AND also add the wolfi-presubmit repository from (1) above as build_repositories in the environment of all of these files

Such PR is not ok to merge into main; but it will correctly retest all builds against the new ICU abi; and will be summarised with build/test failures.

EDIT: wait, I think I am wrong. Because looking at successful builds:
https://apk.chaindag.dev/https/apk.cgr.dev/wolfi-presubmit/9818cc3e9849f05c67c8ab2bce6b32cc92faec1d/aarch64/libarrow-19.0.0-r2.apk@etag:a4012c49af1ceed2275030aa50a50ce0/.PKGINFO

the rebuild of apache did pick up the new icu 76 abi.

xnox is wrong
