Xingbo Jiang 007c873ae3 Prepare Spark release v3.0.0-preview-rc2
### What changes were proposed in this pull request?

To push the built jars to maven release repository, we need to remove the 'SNAPSHOT' tag from the version name.

Made the following changes in this PR:
* Update all the `3.0.0-SNAPSHOT` version name to `3.0.0-preview`
* Update the sparkR version number check logic to allow jvm version like `3.0.0-preview`

**Please note those changes were generated by the release script in the past, but this time since we manually add tags on master branch, we need to manually apply those changes too.**

We shall revert the changes after 3.0.0-preview release passed.

### Why are the changes needed?

To make the maven release repository to accept the built jars.

### Does this PR introduce any user-facing change?

No

### How was this patch tested?
