Use VirtusLab distribution of bazel-bsp (#58)

Updating this extension to transition from JetBrains BSP distribution to
the new fork hosted on https://github.com/VirtusLab/bazel-bsp. No major
functional changes, except for added compatibility for non-Bzlmod repos
on Bazel 8+ (VirtusLab/bazel-bsp#21).

Tested the following commands on Java/Python monorepos:
- Run, Coverage, Debug for individual test cases
- Syncing targets
