[inplace.vector.syn] Missing default template argument for `erase`

[frederick-vs-ja]

The default template argument is present in [inplace.vector.erasure], and it should also be in the synopsis.

Is an LWG issue needed to fix this as the inconsistency was originally in P0843R14?

No, this is obviously editorial:

(the first broad category).

The template arg is present in the detailed description, and is present for all other erase overloads since #6911 so it's an obvious inconsistency that it's missing from the <inplace_vector> synopsis.
