[llvm] [ADT] Fix missing 'template' keyword (PR #98252)

[Krystian Stasiowski via llvm-commits]

https://github.com/sdkrystian created https://github.com/llvm/llvm-project/pull/98252

Fixes instances where the `template` keyword should be used to interpret `<` as the delimiter of a _template-argument-list_ after #92957.
