Missing test coverage for req.is() with an array argument

[webdevelopersrinu]

req.is() is documented to accept either a string or an array of types (see the @param {String|Array} types JSDoc in lib/request.js). Passing loose string arguments and single strings is covered by the test suite, but calling req.is() with an actual array — e.g. req.is(['html', 'json']) — has no test.

Running npm run test-cov confirms this: lib/request.js line 273 (the Array.isArray(types) branch) is the only uncovered branch in the file.

I'd like to add test cases for the array form to close this gap. Happy to open a PR.

Coverage output (npm run test-cov):

File	% Stmts	% Branch	% Funcs	% Lines	Uncovered Line #s
express/lib	98.74	96.16	100	99.61
request.js	100	98.07	100	100	273

In theory #7112 includes tests for it, but I can't force myself to look at the wall of AI slop in that PR.

Opened #7394 with tests for req.is(['html', 'json']) and related array cases.

I don't know how I did not notice it earlier, but there is #6703 (opened a year ago) which addresses this.

I'm going to close this since we don't need an issue for it, and it mostly just attracts AI slop. We appreciate the effort, but there's no need to track this here. At some point, someone from the team will review those test PRs, and if they're valid, they'll be merged
