Update src-cli's user-facing aspects for SCIP

[varungandhi-src]

• I think we should just have a src upload subcommand, instead of src lsif upload or src scip upload. The file extension provides enough context. #748
• Update to the latest scip version that includes this bugfix sourcegraph/scip-typescript#136
  • #751
• Cut a new patch release and update the src-cli generated docs in sg/sg, as part of the documentation work for SCIP.
  • release: #752
  • doc update: https://github.com/sourcegraph/sourcegraph/pull/36050

Previously, I updated the internals in #741.
