Update code so "no-shadow" passes

Two minor code fixes

Abort CodeQL action if the status cannot be reported

Fix a minor issue in the update-release-branch.py script that performs a
call to `sorted` but doesn't use the output. Since `sorted` does not
operate in place, the call is currently useless. As a result, the function
`get_pr_for_commit` does not currently work as exected. I.e. it is
expected to return the "first" (i.e. lowest PR number), but actually it
returns the first in the list provided by GitHub.

The tracer-config.test.js file contained a duplicate of the statement:

  process.env["SEMMLE_DEPTRACE_SOCKET"] = "abc";

one line apart. This removes the second instance of this statement.

- Rename "toolrunnner" (three 'n') to "toolrunner"
- Rename "relativeFilepaht" to "relativeFilepath"
- Fix various typos in documentation & comments
- Fix typos in logs and test names

Rename one instance of "path"  to avoid shadowing.

Rename various instances of "hash", shadowing the function with that
name.

Rename shadowing "uri" argument to the more explicit "artifactURI".

Rename throwaway variable "suite" to "found" when assigned from "find".

Rename local variable "path" to "newPath" as it is a modification of
the "originalPath" provided to `validateAndSanitisePath`.

Rename instances of "path" to more explicit varients "ignorePath" and
"includePath". Maybe "ignoredPath" and "includedPath" are better names?

Rename "queries" variable in test cases to "testQueries" to avoid
shadowing it in a subsequent helper function call (4 times).

Rename "path" twice in a hlper function to "validPath" and "invalidPath"
to avoid shadowing "path". The new names are more explicit.

Two simple variable renames from "path" to "paths" since the types are
arrays of strings (not just one string).

One function definition inside a function moved outside that function
to avoid shadowing the "options" argument.

Duplicate use of "_" placeholder argument name. This change may conflict
with #192.

Remove the "no-shadow": "off" override and replace it by enabling
"@typescript-eslint/no-shadow" in the "rules" section, following the
typescript-eslint docs:
https://github.com/typescript-eslint/typescript-eslint/blob/master/packages/eslint-plugin/docs/rules/no-shadow.md#how-to-use

Check CODEQL_EXTRACTOR_GO_TRACE and treat Go as a traced language

Ensure unqualified program names are present on `PATH` before executing them.

Until there is a more robust versioning system it is probably safest to require endpoint compatiblity and not continue the action if there is a mismatch.
