Add GMRT Runtime support

[KhanDevelopsGames]

Currently, this extension can not be used when using the latest LTS2026 and trying to build using the new GMRT Runtime.

The following error is shown in the output window:

[STEAMWORKS] INIT: Script initialization succeeded (v2.0.0 :: 1).
[STEAMWORKS] ERROR: The LTS runtime version needs to be at least v2022.0.1.24.

Edit:

I have updated to the latest extension version, but the issue remains:

[STEAMWORKS] INIT: Script initialization succeeded (v2.1.6 :: 1).
[STEAMWORKS] ERROR: The LTS runtime version needs to be at least v2022.0.1.24.

Support for LTS2026 should be added.

I have also tried updating my extension, but received the following error when trying to import it to my project:

Cannot load project or resource because loading failed with the following errors:
=== The JSON file reader encountered parsing errors ===
.../Steamworks.yyp(2,3): Error: A type tag field is required at the start of the JSON record, eg: "$MyTypeName": ...

I have managed to import the latest extension by converting the demo project to the new project format, and then importing the extension from the converted project, however, the issue remains.

[STEAMWORKS] INIT: Script initialization succeeded (v2.1.6 :: 1).
[STEAMWORKS] ERROR: The LTS runtime version needs to be at least v2022.0.1.24.

Can't reproduce with my IDE & Runtime installations, are you sure you have the matching runtime installed and you're on the latest version of the extension (2.2.1)?

@KhanDevelopsGames I'm on an even older version of the Steamworks extension version (v2.1.4), I am not having this issue at all.

Is your IDE/Runtime mismatched in anyway?

Also for clarity, here is my IDE/Runtime.

sorry, i should have clarified that this issue only exists when trying to use the GMRT Runtime. I have edited the issue accordingly

GMRT is still in beta at the moment, and the team hasn't released their v0.20 update yet. Extension support might be a fair bit away before then.
