Quickfix Acorn\PackageManifest: ${composerPath} -> {$composerPath}

[sybbear]

Hello,
this makes 3 small fixes that stops php from producing
[WARNING: Using ${var} in strings is deprecated, use {$var} instead]

Please make a new release, if it is easy to do on this 2.x branch, so we can enjoy cleaner logs

The same issue is present with version 3, however since version 4 seems fixed (search by ${)

Best regards

[sybbear]

Any chance to merge this?
@retlehs or someone for the team

Totally harmless fix, however significantly reduces log noise

[retlehs]

Would prefer not to merge anything or release anything for Acorn 2.x

[Log1x]

Is there any particular reason you can't upgrade? The upgrade path should be pretty smooth.

[sybbear]

@retlehs @Log1x
Roots/acorn 3 requires L9 and version 4 requires L10
We have a pretty large system that relies on L8 and we can't upgrade it of now due to vendor constraints.

Is there something else we could do other than forking this?
I'd write tests for this PR, but there are no tests to write for these kind of changes, since the logic is exactly the same, just correct string interpolation

If you could possibly consider 🙏 😄
