ORC-2108: Add connection timeout to JIRA client to prevent hanging and enable retries

### What changes were proposed in this pull request?

This PR aims to add a generic connection and read timeout parameter timeout=(3.05, 30) to the `jira.client.JIRA()` initializations in the dev/ scripts:
- `create_orc_jira.py`
- `merge_orc_pr.py`

### Why are the changes needed?

By default, the requests library (used by the jira python package) can hang indefinitely when attempting to establish a connection if the server is unresponsive. Setting a short connection timeout of 3.05 seconds (slightly larger than a standard 3-second TCP packet retransmission window) ensures that the client will quickly fail the connection attempt and properly trigger its internal retry logic, rather than stalling the entire script. The 30-second read timeout allows sufficient time for normal API responses once the connection is successfully established.

### How was this patch tested?
