8392: Add space after lifetime in expand macro r=edwin0cheng a=sharksforarms

When a lifetime is followed by an ident, this lead to invalid syntax. This adds a whitespace between the lifetime and the identifier.

Noticed this here: https://github.com/simrat39/rust-tools.nvim/issues/2#issuecomment-814551847
