Description

The ng update from version 14 to 15 migration fails with the following nondescript error if you have a node_modules "backup", for example node_modules2, folder in the project directory

This is technically "my fault", but it would be nice if we had a better description of what is going on, I had to add a bunch of logs to the cli code to figure out where and what made it fail.

Here is the specific error:

Remove Browserslist configuration files that matches the Angular CLI default configuration.
× Migration failed: Unknown browser query `basedir=$(dirname "$(echo "$0" | sed -e 's`. Maybe you are using old Browserslist or made typo in query.
  See "<logs>\angular-errors.log" for further details.

Minimal Reproduction

Arrange your directories in the following fashion:

├───angular-root-directory
│ ├───node_modules
│ ├───node_modules2
│ ├───src
│ ├───package.json
│ ├───angular.json
│ ├───tsconfig.json

And run the @angular/cli migrations with a command equivalent to this one:
ng update @angular/cli --from 14 --to 15 --migrate-only --allow-dirty --force

The node_modules2 directory must have the npm packages too.

The specific cause of the "crash" is the presence of the browserslist file in /node_modules2/.bin/ because line 80 of
@schematics\angular\migrations\update-15\remove-browserslist-config.js tries to parse the source of the browserslist executable
Here is "my" line 80: const { defaults: browsersListConfig, ...otherConfigs } = browserslist.parseConfig(tree.readText(path));

Exception or Error

Remove Browserslist configuration files that matches the Angular CLI default configuration.
× Migration failed: Unknown browser query `basedir=$(dirname "$(echo "$0" | sed -e 's`. Maybe you are using old Browserslist or made typo in query.
  See "<logs>\angular-errors.log" for further details.


Actual log:
[error] BrowserslistError: Unknown browser query `basedir=$(dirname "$(echo "$0" | sed -e 's`. Maybe you are using old Browserslist or made typo in query.
