`try_reserve_exact` documentation says to "Prefer `reserve`"

[8573]

The documentation comments of the three try_reserve_exact methods stabilized today in 1.57.0 (in Vec, String, and VecDeque) all have the same note as the corresponding aborting method reserve_exact:

Prefer reserve if future insertions are expected.

For the fallible try_reserve_exact methods, should that say try_reserve rather than reserve?
