[BUG]pioarduino compatibility seems broken in bugfix and 2.1.3 prereleases

[luc-github]

I am porting latest ESP3D 3,0.0 beta 1 to ESP3DLib
Because espressif does not support platformio then platformio dropped the support of arduino esp32 core after latest 2.x version which correspond to IDF 4..4.7, to get support of idf 5.1+ which means esp32 arduino core 3.x a community version of platformio for esp32 core has been created :
https://github.com/pioarduino/platform-espressif32

so in platformio.ini need to use for esp32 arduino core 3.0.4 (idf: 5.1.4) :

 ; Arduino  core 3.0.4 - IDF 5.1.4
platform = https://github.com/pioarduino/platform-espressif32/releases/download/51.03.04/platform-espressif32.zip

this seems to work with Marlin 2.1.2.5 release, I am doing the porting now
but latest bugfix failed immediatly to compile with 'CC' not found error
I have tested 2.1.3 beta 1, 2.1.3 beta 2 and latest bugfix, I was not able to find the root cause yet because 2.1.2.x and 2.1.3.x use different branchs and code base.

I will try to finish the porting and test this week 2.1.2.5 fork to confirm it is ok, and open issue in Marlin repository for the compatibility issue of 2.1.3 with https://github.com/pioarduino/platform-espressif32
