[BUG] typesafe-api code generation script doesn't handle spaces in the directory path

Describe the bug

Running pnpm build in a directory that contains spaces in the path will cause the typesafe-api generate task to fail.

Expected Behavior

@redacted/api-model: 👾 build » compile » generate | npx --yes -p @aws/pdk@$AWS_PDK_VERSION type-safe-api.parse-openapi-spec --spec-path build/smithyprojections/@redacted-api-model/openapi/openapi/api.openapi.json --output-path .api.json --smithy-json-path build/smithyprojections/@redacted-api-model/openapi/model/model.json

@redacted/api-model: openapi-spec parsed

The previous output is from a project without a space in the directory, the openapi file is parsed correctly and the build continues.

Current Behavior

The following terminal output occurs when there is a space in the directory name. Then the build fails

@redacted/api-model: 👾 build » compile » generate | npx --yes -p @aws/pdk@$AWS_PDK_VERSION type-safe-api.parse-openapi-spec --spec-path build/smithyprojections/@redacted-api-model/openapi/openapi/api.openapi.json --output-path .api.json --smithy-json-path build/smithyprojections/@redacted-api-model/openapi/model/model.json

@redacted/api-model: Warning: run-commands command "pnpm dlx projen build" exited with non-zero status code

Reproduction Steps

Create a new project in a directory that contains a space in the directory name
Run pnpm build

Possible Solution

The generate task parsing script may have an error at the following line or above

aws-pdk/packages/type-safe-api/scripts/type-safe-api/parser/parse-openapi-spec

Line 16 in 6fc5ca1

    
           script_dir="$( cd -- "$(dirname $([ -L "${BASH_SOURCE[0]:-$0}" ] && readlink -f "${BASH_SOURCE[0]:-$0}" || echo "${BASH_SOURCE[0]:-$0}"))" >/dev/null 2>&1 ; pwd -P )";
