Limits the issue list to 30 while generating release notes

When I try to generate release notes which has issues more than 30, it ignores the the issues after 30th issue. Below is the logs I am getting while generating relase notes.

```
🤖 - Generate release notes:
===================================
✔ Releases found: 1
✔ Tags found: v1.0, starting_v1.0_implementation
✔ Issues found: 30

```

May I know, how we can change the count of issues to be consider while generating notes.
