Fix PyOutline package name typo in installation docs (#2071)

**Link the Issue(s) this Pull Request is related to.**
Fixes #2065

**Summarize your change.**
This PR fixes a typo in the PyOutline installation documentation where
the package name was misspelled as `opencue-pyotline` instead of
`opencue-pyoutline`.

**Changes made:**
- Changed `opencue-pyotline` to `opencue-pyoutline` in
`/docs/_docs/getting-started/installing-pycue-and-pyoutline.md`

**Why this change is needed:**
The current documentation shows an incorrect command that results in a
package not found error when users try to install PyOutline. This
prevents users from successfully setting up OpenCue components.

**Testing performed:**
- Verified that `pip install opencue-pyoutline` works correctly
- Confirmed that `pip install opencue-pyotline` produces the expected
package not found error
- The change is a straightforward documentation correction with no
functional code changes
