fix: reference correct octokit action for creating release

[bianchidotdev]

Hello! This is for a fix for creating GitHub releases (#67 )

What I've done:

1. Updated octokit command for createRelease
2. Verified no existing tests have regressed

lerna success run Ran npm script 'lint' in 6 packages in 6.8s:
lerna success - @geut/chan-core
lerna success - @geut/chan-stringify
lerna success - @geut/chan
lerna success - @geut/chast
lerna success - @geut/git-url-parse
lerna success - @geut/remark-chan

3. Verified new code creates release successfully

 λ npm link
 λ chan added "New chan release"
[chan] [added] › ✔  success   Added new changes on your changelog.
 λ chan release 0.1.4
[chan] [release] › ✔  success   New release created. 0.1.4
 λ export GITHUB_TOKEN=<REDACTED>
 λ chan gh-release 0.1.4
[chan] [gh-release] › ℹ  info      Uploading GitHub release...
[chan] [gh-release] › ✔  success   GitHub release created.

What I did not do:

1. Write new tests to validate this behavior 😞 - I really have no idea how I would do that here in js
