Fix php-wasm build error for WITH_SOURCEMAPS=yes (#44)

## Motivation for the change, related issues

Building php-wasm with WITH_SOURCEMAPS=yes is currently broken. When
WITH_SOURCEMAPS is enabled, it turns out Emscripten is generating JS
that uses single quotes rather than double-quotes. I guess this has to
do with the difference in optimization options but have not tested it.

## Implementation details

This PR fixes the build so there is no longer an error by expanding the
php-wasm JS replacement regexes to match on either single or double
quotes. I have not tested actually debugging with sourcemaps, but this
fixes the build error.

Once this is fixed I plan add a build arg for compiling php-wasm with
DWARF debug info so we [can step-through-debug the PHP runtime in
Chrome](https://developer.chrome.com/docs/devtools/wasm) with access to
variable values.

## Testing Instructions (or ideally a Blueprint)

Run the following command on trunk and on this branch, and note that it
fails on trunk and succeeds on this branch.
```
npx nx recompile-php:asyncify php-wasm-web -- --PHP_VERSION=8.4 --WITH_SOURCEMAPS=yes
```
