build: fix release workflow

The workflow has been updated in #197 but is failing now with:

```
[warning]Unexpected input(s) 'go-version', valid inputs are ['path', 'key', 'restore-keys', 'upload-chunk-size', 'enableCrossOsArchive', 'fail-on-cache-miss', 'lookup-only']
[group]Run actions/cache@88522ab
with:
  go-version: 1.18
  enableCrossOsArchive: false
  fail-on-cache-miss: false
  lookup-only: false
[endgroup]
[error]Input required and not supplied: key
```
