drop unsupported dependencies, support php 8.4

this release drops support for Symfony < 6.4 and PHP < 8.2.

Version 1.0

I'm publishing a 1.0 release because github handles releases less than 1.0 a bit differently.

Plus, I wanted to prepare for a 2.0 release which will drop support for unmaintained version of Symfony and PHP.

I'm somewhat new to the world of publishing releases. Hopefully I've done it right!

v0.18.1

Symfony 5 compatibility

v0.18.0

PHP8 Support

v0.9.0

Breaking changes

• enum_titles are not anymore rendered in a liform subarray in the schema, but in the same format that liform-react understands. Limenius/liform-react#7
• buildLiform callback receives and returns a schema instead of building a liform subarray.
