Big package size due to un-deduplicated copy of typescript

Currently the effective package size of @nest/cli is 34MB, mainly because the package requires a pinned version of typescript, which make npm/yarn unable to deduplicate typescript package. Can we loosen the version requirement for typescript?

% du -sh node_modules/@nestjs/cli | sort -h 
 34M    node_modules/@nestjs/cli
% du -sh node_modules/@nestjs/cli/node_modules/* | sort -h
164K    node_modules/@nestjs/cli/node_modules/cosmiconfig
740K    node_modules/@nestjs/cli/node_modules/fork-ts-checker-webpack-plugin
1.1M    node_modules/@nestjs/cli/node_modules/glob
 31M    node_modules/@nestjs/cli/node_modules/typescript

"typescript": "5.7.2",

Describe the solution you'd like

Change typescript version to something like "^5.7.2".

What is the motivation / use case for changing the behavior?

Solving this can reduce network cost and build time in local development and CI. This package @nest/cli has about 2 million downloads per week, excluding typescript (4MB after gzip) can save 8TB / per week of transfer cost, which is about $600 USD of CDN hosting cost per week.

I think that we should use ~ instead of ^ because, if I'm not wrong, sometimes typescript bumps the minor slice introducing breaking changes to the compiler API (which Nest's CLI uses under the hood)
