deps: update dependency com.google.cloud:google-cloud-pubsub to v1.13.17. with temp fix.

[zhumin8]

This intends to fix issue in googleapis/java-cloud-bom#6050 (comment)
dependency tree for j2objc-annotations without this fix:

[INFO] --------------< com.google.cloud:google-cloud-pubsublite >--------------
[INFO] Building Google Cloud Pub/Sub Lite 1.12.10-SNAPSHOT                [4/5]
[INFO] --------------------------------[ jar ]---------------------------------

[INFO]    \- com.google.j2objc:j2objc-annotations:jar:1.3:compile

• With out declaring version for google-cloud-pubsub here, it's getting 1.123.14 (new shared-dependencies included in v1.123.15). I think this should be updated as part of deps: update dependency com.google.cloud:google-cloud-pubsub to v1.123.17 #1444. (pubsub is a blocker for pubsublit release) Is this sufficient to be picked up by bot in future upgrades?
• Then the temp fix is needed because j2objc-annotations:jar:1.3 in protobuf 3.23.2 and we could not upgrade to 3.23.3 due to missing protoc prebuilds in maven central (Maven central does not have protoc prebuilts protocolbuffers/protobuf#13070). Similar fix implemented in deps: update dependency com.google.cloud:google-cloud-shared-dependencies to v3.12.0.with temp exclusions. java-spanner#2512 and will be removed on next protobuf upgrade. (will add this to internal bug as reminder when we decide to merge this in.)

After this fix:
