v3 Theme Generator legacy theme import doesn't support comments

[endigo9740]

Current Behavior

If the v2 theme source contains comments, you'll see the following error:

Expected Behavior

By stripping out all comments, the theme will import as expected. Ideally we should strip the comments automatically for users as the raw v2 generator export includes these comments.

Steps To Reproduce

1. Generate a new v2 theme
2. Export to a theme.ts file
3. Try import this via the v3 generator import feature
4. The theme will fail with the above error
5. Strip out any and all comments ad import again
6. The theme will import as expected

My sneaky suspicion is that those comments at end of lines in the v2 theme source are causing this trouble. The comments that have their own lines shall be fine.

// This line is fine
// primary | #c93655
// This line shall not pass 
"--color-primary-50": "247 225 230", // #f7e1e6

The parsing done in import-file.ts doesn't account for comments at the end of a line.

EDIT: I'm pretty sure that's the cause, it's not a sneaky suspicion.

@phamduylong likely so, but don't worry about this. Hugo has volunteered to upgrade the portion that parses the file contents using the knowledge he's accrued from writing the migration CLI. It's a similar concept reading/parsing file contents, rather than how I'm doing it (reading it as text content).

@Hugos68 I'll go ahead and assign this one to you to represent those changes.
