tlmgr needs self-update on 2026.03.02

I think something was updated in the latest texlive repository that forces tlmgr to ask for a self-update: ``` =============================================================================== tlmgr itself needs to be updated. Please do this via either tlmgr update --self or by getting the latest updater for Unix-ish systems: https://mirror.ctan.org/systems/texlive/tlnet/update-tlmgr-latest.sh and/or Windows systems: https://mirror.ctan.org/systems/texlive/tlnet/update-tlmgr-latest.exe Then continue with other updates as usual. =============================================================================== tlmgr: Terminating; please see warning above! ``` Can the updated tlmgr be included in the next release?
