docs: fix typos in prebuilt-binaries.md and release-guide.md (#4030)

## Overview

**Description**:
This pull request addresses two spelling errors in the documentation
files:

1. **In `docs/maintainers/prebuilt-binaries.md`**:
   - The word **occured** is corrected to **occurred** (with two "r"s).
   
2. **In `docs/maintainers/release-guide.md`**:
- The word **relase** is corrected to **release** (with an extra "e").

**Importance**:
These spelling corrections ensure that the documentation is accurate and
professional. Correct spelling is important in maintaining clarity and
trust in the documentation, especially for new contributors and users.
It also improves searchability, as users may encounter issues when
searching for these terms with the incorrect spelling.
