[CALCITE-5007] Upgrade H2 database version to 2.1.210

The 1.4.197 version suffers from multiple CVEs such as:
https://nvd.nist.gov/vuln/detail/CVE-2018-14335
https://nvd.nist.gov/vuln/detail/CVE-2018-10054
https://nvd.nist.gov/vuln/detail/CVE-2021-42392
https://nvd.nist.gov/vuln/detail/CVE-2022-23221

In the project, we use H2 only for testing purposes thus the H2
binaries are not present in the runtime classpath thus these CVEs do
not pose a problem for Calcite or its users.
