Correctly support linguist-documentation=false
If a documentation file is marked with a `linguist-documentation=false`
attribute, include it in language stats.

However, make sure that we do *not* include documentation languages as
fallback.

Added a new test case to exercise the formerly buggy behaviour.

Problem discovered while reviewing @KN4CK3R's tests from gitea#29267.

// While this is a fairly short test, this exercises a number of

//
// - `.gitattributes` is empty, so `isDetectable.IsFalse()`,
// `isVendored.IsTrue()`, and `isDocumentation.IsTrue()` will be
// false for every file, because these are only true if an
// attribute is explicitly set.
//
// - There is `.dot.pas`, which would be considered Pascal source,
// but it is a dotfile (thus, `enry.IsDotFile()` applies), and as
// such, is not considered.
//
// - `some-file.xml` will be skipped because Enry considers XML
// configuration, and `enry.IsConfiguration()` will catch it.
//
// - `!isVendored.IsFalse()` evaluates to true, so
// `analyze.isVendor()` will be called on `cpplint.py`, which will
// be considered vendored, even though both the filename and
// contents would otherwise make it Python.
//
// - `!isDocumentation.IsFalse()` evaluates to true, so
// `enry.IsDocumentation()` will be called for `docs.md`, and will
// be considered documentation, thus, skipped.
//
// Thus, this exercises all of the conditions in the first big if
// that is supposed to filter out files early. With two short asserts!
