Generation is taking >4 minutes for a schema with 400 models

Nobody has claimed this yet.

**Describe the Bug**
Generator typegraphql-prisma is taking >4 minutes compared to prisma client for a schema with >400 models while prisma client takes just under 1-2 seconds. Is this expected behaviour ?

**To Reproduce**
Run npx prisma generate on a schema with lot of models with below generator

```
generator typegraphql {
provider = "typegraphql-prisma"
useOriginalMapping = "true"
}
```

**Expected Behavior**
I would expect it to be taking just a few seconds to generate everything.

✔ Generated TypeGraphQL integration to ./../node_modules/@generated/type-graphql in 409.73s

**Environment (please complete the following information):**

OS: Mac M3

```
"@prisma/client": "^5.20.0",
"prisma": "^5.20.0",
"ts-node": "^10.9.2",

```

**Additional Context**
Saw the same issue as closed here - [Issue](https://github.com/MichalLytek/typegraphql-prisma/issues/90)
I have tried the steps mentioned here but have not been able to bring the time down

Appreciate any help here , thanks in advance !

Reproduce the report with npx prisma generate, a schema containing more than 400 models, and the shown typegraphql generator configuration. Compare the Prisma Client and TypeGraphQL integration timings in the logs, then review the earlier issue 90 for relevant context. Done means identifying the cause of the 409.73-second generation time and implementing or documenting a measured improvement toward the expected few-second runtime.
