[2.x] chore: require the sourcemap release carrying the 8.5 deprecation fix (#4904)

`axy/sourcemap` 1.1.1 reorders the two guards in `Line::concat()` that read an
array before checking the index is not null, which PHP 8.5 reports once per
mapped position — hundreds of lines per request while compiling assets on a
debug install (#4894, fixed upstream in axypro/sourcemap#13).

`^1.1` already resolved to it, so this changes nothing for a fresh install. It
is here to say so: the version we need is 1.1.1, not merely whatever 1.x
resolves to today.

Verified on PHP 8.5 that `JsCompiler`'s concat path no longer emits the notice,
with byte-identical sourcemap output.
