uberon Add specific bronchopulmonary segment terms for HCA lung dataset

Summary

This PR adds 18 new bronchopulmonary segment terms to support anatomical annotation of lung samples in the Human Cell Atlas (HCA) CELLxGENE dataset, as requested in #3444.

Terms Added

Right lung (10 segments):

Upper lobe of right lung (UBERON:0002170):
- UBERON:9900001 right apical bronchopulmonary segment
- UBERON:9900002 right posterior bronchopulmonary segment
- UBERON:9900003 right anterior bronchopulmonary segment
Middle lobe of right lung (UBERON:0002174):
- UBERON:9900004 right lateral bronchopulmonary segment
- UBERON:9900005 right medial bronchopulmonary segment
Lower lobe of right lung (UBERON:0002171):
- UBERON:9900006 right superior bronchopulmonary segment
- UBERON:9900007 right medial basal bronchopulmonary segment
- UBERON:9900008 right anterior basal bronchopulmonary segment
- UBERON:9900009 right lateral basal bronchopulmonary segment
- UBERON:9900010 right posterior basal bronchopulmonary segment

Left lung (8 segments):

Upper lobe of left lung (UBERON:0008952):
- UBERON:9900011 left apical-posterior bronchopulmonary segment
- UBERON:9900012 left anterior bronchopulmonary segment
- UBERON:9900013 left superior lingular bronchopulmonary segment
- UBERON:9900014 left inferior lingular bronchopulmonary segment
Lower lobe of left lung (UBERON:0008953):
- UBERON:9900015 left superior bronchopulmonary segment
- UBERON:9900016 left antero-medial basal bronchopulmonary segment
- UBERON:9900017 left lateral basal bronchopulmonary segment
- UBERON:9900018 left posterior basal bronchopulmonary segment

Term Structure

Each term includes:

Logical definitions: intersection_of axioms properly linking each segment to its parent lung lobe (UBERON:0002170, UBERON:0002174, UBERON:0002171, UBERON:0008952, UBERON:0008953) and the bronchopulmonary segment class (UBERON:8600017)
Definitions: Based on anatomical location and bronchial supply, referenced to PMID:18271171
Synonyms: Including standard clinical terminology and segment numbering (S1-S10)
Metadata: Proper contributor attribution (Gloria S. Pryhuber, ORCID:0000-0002-9185-3994), timestamps, and issue tracking

Pulmonary Arterial Branches

As noted in the issue comments by @gpryhuber, each bronchopulmonary segment is supplied by its own bronchus and pulmonary arterial branch. This anatomical organization allows segments to be functionally and anatomically discrete, permitting surgical resection of individual segments. While I didn't add specific arterial branch relationships in this initial implementation (as detailed pulmonary arterial terminology would need to be verified/added to UBERON first), this could be a future enhancement.

Clinical Significance

As noted by @gpryhuber, bronchopulmonary segments are particularly important in:

Radiology interpretation
Thoracic surgery planning
Understanding infection patterns (segments are separated by connective tissue, which can restrict infection spread)
Functional independence allowing segmentectomy
