DRIVERS-716 skip bulkWrite tests on Atlas Serverless

[kevinAlbs]

Summary

Follow-up to #1534. Skip tests running bulkWrite on Atlas Serverless.

Background & Motivation

CLOUDP-256344 blocks bulkWrite in Atlas Serverless. This can be seen with mongosh:

Atlas test> db.version()
8.0.0-rc17
Atlas test> db.adminCommand({bulkWrite: 1, ops: [{insert: 0, document: {foo: "bar"}}], nsInfo: [{ns: "db.coll"}]})
MongoServerError[AtlasError]: (Unauthorized) not authorized on admin to execute command { bulkWrite: 1, ops: [[{insert 0} {document [{foo bar}]}]], nsInfo: [[{ns db.coll}]], lsid: { id: {4 [149 137 108 46 117 126 74 218 185 29 250 199 40 40 23 131]} }, $clusterTime: { clusterTime: {1724242370 2}, signature: { hash: {0 [31 9 179 21 13 4 43 10 142 148 251 52 224 5 220 242 224 236 216 151]}, keyId: 7364078628537106432.000000 } }, $db: "admin" }

Some unified tests required increasing schemaVersion to 1.4 to include support specifying serverless as a runOnRequirement.

---

Please complete the following before merging:

• [ ] Update changelog.
• Make sure there are generated JSON files from the YAML test files.
• Test changes in at least one language driver. (Tested in Python)
• Test these changes against all server versions and topologies (including standalone, replica set, sharded
  clusters, and serverless).

@shruti-sridhar may I request trying these test files with the Python implementation? C does not currently test serverless in Evergreen, and Rust has an open ticket to investigate serverless test failures.

I tested these on the serverless Evergreen tasks with the Python implementation and they're successfully skipped! They also pass on the 8.0 standalone, replica set, and sharded cluster tasks. Here's the link to the run.

LGTM, changes pass in Rust
