feat: bump client to v0.2.26 and add CRC32FromStrings func

[gaius-qi]

Description

This pull request introduces changes to enhance functionality, update dependencies, and improve test coverage. The most significant updates include the addition of a new CRC32FromStrings function for generating checksums, updates to compatibility tests, and modifications to e2e tests for persistent cache task ID generation.

Functionality Enhancements:

• Added a new CRC32FromStrings function in pkg/digest/digest.go to compute CRC32 checksums from multiple strings. This function is used for generating persistent cache task IDs.
• Introduced a PersistentCacheTaskIDByContent function in pkg/idgen/task_id.go that utilizes CRC32FromStrings to generate task IDs for persistent caching.

Dependency Updates:

• Updated the image tag for client and seed-client in .github/workflows/compatibility-e2e-v2.yml from v0.2.18 to v0.2.26.
• Updated the client-rs submodule to a new commit (a15d556f959ff75c302608c6297f654fcb546f30).

Test Coverage Improvements:

• Added a unit test for the CRC32FromStrings function in pkg/digest/digest_test.go.
• Added a unit test for the PersistentCacheTaskIDByContent function in pkg/idgen/task_id_test.go.
• Updated e2e tests in test/e2e/v2/dfcache_test.go to use PersistentCacheTaskIDByContent for task ID generation, replacing direct SHA256 usage. This change ensures consistency in persistent cache task ID generation. [1] [2] [3] [4] [5]
