Patch Changes

#7859 c600618 Thanks @Netail! - Added the nursery rule noIncrementDecrement, disallows the usage of the unary operators ++ and —.
#7901 0d17b05 Thanks @ematipico! - Fixed #7837, where Biome couldn’t properly parse text expressions that contained nested curly brackets. This was breaking parsing in Astro and Svelte files.
#7874 e617d36 Thanks @Bertie690! - Fixed #7230: noUselessStringConcat no longer emits false positives for multi-line strings with leading + operators.

Previously, the rule did not check for leading newlines on the + operator, emitting false positives if one occurred at the start of a line.
Notably, formatting with operatorLinebreak="before" would move the + operators to the start of lines automatically, resulting in spurious errors whenever a multi-line string was used.

Now, the rule correctly detects and ignores multi-line concatenations with leading operators as well, working regardless of the setting of operatorLinebreak.

Example
```
1
// The following code used to error if the `+` operators were at the start of lines (as opposed to the end).
2
// Now, the rule correctly recognizes this as a stylistic concatenation and ignores it.
