Change release process to make releases immutable

[robert3005]

Document that binaries have to be built manually when making a release to allow
us to make releases immutable. Instead of appending binaries to an existing
release on publish we append them to draft and only publish once they're
populated

⚠️ Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data.

For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.

⚠️ Different runtime environments detected

Some benchmarks with significant performance changes were compared across different runtime environments,
which may affect the accuracy of the results.
