fix: working tinygo target.json

[matm]

Trying the hello-world project, running make using Go returns several build errors with the current target.json template file.

This PR fixes them by using a working template (should close issue #595).

Currently the errors are:

[wasm-validator error in function 0] unexpected false: Bulk memory operations require bulk memory [--enable-bulk-memory], on
(memory.fill
 (i32.const 14856)
 (i32.const 0)
 (i32.const 905)
)
[wasm-validator error in function 5] unexpected false: Bulk memory operations require bulk memory [--enable-bulk-memory], on
(memory.copy
 (local.get $0)
 (local.get $1)
 (local.get $2)
)
[wasm-validator error in function 6] unexpected false: Bulk memory operations require bulk memory [--enable-bulk-memory], on
(memory.fill
 (local.get $0)
 (local.get $1)
 (local.get $2)
)
[wasm-validator error in function 11] unexpected false: Bulk memory operations require bulk memory [--enable-bulk-memory], on
(memory.copy
 (local.get $0)
 (local.get $1)
 (local.get $2)
)
Fatal: error validating input
wasm-opt failed: exit status 1

The hello-world project compiles successfully with this patch.

Note: tested with Go 1.23.3 and tinygo 0.34.0 (linux/amd64)
