dishaprakash 341316bb63 chore: Update Version String (#2380)
## Description

This PR modifies the User Agent (version string) generation to better
accommodate the recent support for combining prebuilt and custom tools.

The design for this update is as so:
Single Prebuilt: <version+metadata>+prebuilt.bigquery
Multiple prebuilt: <version+metadata>+prebuilt.bigquery+prebuilt.alloydb
Prebuilt + Custom:  <version+metadata>+custom.bigquery
Multiple prebuilt + custom:
<version+metadata>+custom.bigquery+custom.alloydb

Versioning Logic:
- Single Prebuilt: Appends +prebuilt.<name>
  Example: ```<version>+prebuilt.bigquery```

- Multiple Prebuilt: Appends a tag for each prebuilt config.
  Example: ```<version>+prebuilt.bigquery+prebuilt.alloydb```

- Prebuilt + Custom: If custom tools are detected, the tag for all
prebuilt tools switches to custom.
  Example: ```<version>+custom.bigquery```

- Multiple Prebuilt + Custom: All prebuilt tools receive the custom tag.
  Example: ```<version>+custom.bigquery+custom.alloydb```
