Remove spaces and/or line-breaks from empty curly braces

[IndrajeetPatil]

According to cf. https://style.tidyverse.org/syntax.html?q=empty%20curly%20braces#indenting, following

library(styler)

style_text(
  "while (waiting_for_something()) {  }"
)
#> while (waiting_for_something()) {  }


style_text(
  "while (waiting_for_something()) {

}"
)
#> while (waiting_for_something()) {
#> 
#> }

^{Created on 2024-10-02 with reprex v2.1.1}|

should instead be styled to:

while (waiting_for_something()) {}
