fix(typescript): TSConfig `compilerOptions` can be optional (projen#3436

)

Fixes projen#3411

Note: Still unable to make an empty `compilerOptions` (without providing one with everything explicitly set to `undefined`) due to `TypeScriptProject` forcing an override. I'll make another issue and PR for that.

Apologies to @coleHafner if they've already spent time on this

fix(python): generated `pyproject.toml` has correct formatting style …

…when using Poetry (projen#3405)

This PR fixes the following issues:
- TOML sections indentation (.e.g `[tool.poetry.dependencies]` section)
- Spaces surrounding string values within square brackets (e.g. `[ "poetry-core" ]`)

#### pyproject.toml (before)
```toml
# ~~ Generated by projen. To modify, edit .projenrc.py and run "npx projen".

[tool.poetry]
name = "example"
version = "0.1.0"
description = ""
authors = [
  "First Last <email@example.com>"
]
readme = "README.md"

  [tool.poetry.dependencies]
  aws-cdk-lib = "^2.130.0"
  constructs = "^10.0.5"
  python = "^3.8"

[tool.poetry.group.dev.dependencies]
projen = "0.80.1"
pytest = "7.4.3"

[build-system]
requires = [ "poetry-core" ]
build-backend = "poetry.core.masonry.api"
```

#### pyproject.toml (after)
```toml
# ~~ Generated by projen. To modify, edit .projenrc.py and run "npx projen".

[tool.poetry]
name = "example"
version = "0.1.0"
description = ""
authors = [
  "First Last <email@example.com>"
]
readme = "README.md"

[tool.poetry.dependencies]
aws-cdk-lib = "^2.130.0"
constructs = "^10.0.5"
python = "^3.8"

[tool.poetry.group.dev.dependencies]
projen = "0.80.1"
pytest = "7.4.3"

fix(cli): unclear error messages when using `projen new` with `--from` (

projen#3385)

Improvement to error handling and error messages thrown in cases where `--from` flag is used (ex: `npx projen new --from [SPECIFIED-NPM-PACKAGE]`).

This PR covers the cases:
* where npm package specified does not exist in the registry and gracefully handles error with informative message to user
* where npm package specified is not jsii module and gracefully handles error with informative message to user
* add additional tests

fix(tsconfig): support three missing strict tsconfig `compilerOptions` (

projen#3409)

This is adding support for `compilerOptions` used [in the wild](https://github.com/tsconfig/bases/blob/main/bases/strictest.json) and escape hatches had to be used.

This was found when applying [@tsconfig/strictest](https://github.com/tsconfig/bases?tab=readme-ov-file#strictest-tsconfigjson) and working around TypeStrong/ts-node#1958 (merged, but not yet released, a year later)

No issue was created, and no tests were added. This is merely a pass-thru to tsconfig (like the existing options above them in the code).
