0.5.0

Improvements:

• Add preliminary support for Go 1.21
  • preliminary support in this case means that cachi2 explicitly always sets GOTOOLCHAIN=local to force Go always use the bundled toolchain that came with the SDK
  • for projects building with Go < 1.21 a 1.20 toolchain will be downloaded to avoid the new 1.21 behaviour of bumping older go.mod files and thus tainting the input repository
