test: skip [email protected] in TAV tests to workaround npm v6 install issue with github deps

[email protected] (and only that version) has a github dep:
    "@types/mysql": "types/mysql",
Attempting to install that version with npm v6 (the npm in node v10, v12, and
v14) hits npm/cli#4896 which results in an
install so slow that is hits the default 2 minute 'npm install' timeout
in the `tav` tool.
