[TF-M] TF-M v2.3.0 is postponed to Q2 2026

Hello,

I would like to inform the community that the TF-M v2.3.0 release has been postponed to April 2026 in order to incorporate the forthcoming PSA-Crypto LTS release, anticipated in Q1 2026. This decision is intended to ensure improved long-term alignment between two projects.

I apologize for any inconvenience the delay may cause and appreciate your understanding.

Best regards, Anton
