SHA256 mismatch for Fluent Bit 4.2.0 Windows files

[ec-motake]

Bug Report

Describe the bug The SHA256 checksums listed on the official documentation for Fluent Bit 4.2.0 Windows files (fluent-bit-4.2.0-win64.exe and fluent-bit-4.2.0-win64.zip) do not match the actual downloaded files. Multiple environments (Windows PowerShell and Ubuntu sha256sum) produce the same hash, which differs from the official values.

To Reproduce

• Download the files from the official Fluent Bit downloads page: https://docs.fluentbit.io/manual/installation/downloads/windows

• Compute SHA256:

  • Windows PowerShell: Get-FileHash -Algorithm SHA256
  • Linux/Ubuntu: sha256sum

• Compare with official checksums:

  • .exe official: ACC3F1B6CA36DF1FD9454788B493EE9DFF61A1980C292C074C868689EC96E52
  • .exe actual: EAE4331606A6E5146E04451B67512687BFD09B013F1C438EE73CB433CA4C2684
  • .zip official: D3F85AEC36CF8D2977BC9224FDEA109F7DE2DE86720388E1F432057AC9380793
  • .zip actual: 4BCB638DF0C579A46E75BE919BA677491D2313EFC989B32FDB86DE13D8B58CDD

Expected behavior The official SHA256 checksums should match the actual downloaded files.

I think this is down to some CI changes/issues, I've not had a chance to investigate it yet but I thought there was another issue raised around this earlier as well so trying to find that.
