Update less dependency version

[hetzge]

While starting the application i got the following error:

=> Errors prevented startup:

   While selecting package versions:
   error: No version of less satisfies all constraints: @2.8.0, @=3.0.1
   Constraints on package "less":
   * less@2.8.0 <- top level
   * less@=3.0.1 <- top level

=> Your application has errors. Waiting for file change.

This change fixed the problem for me. I am using Meteor 1.12.

Hi, thanks for the PR. The current version of the tool (with less 2.8.0, Meteor 1.12) is working on my side using OSX. What OS are you using to get this error?

I am using Windows 10 and have Meteor installed by cloning the Git Repository and running the meteor.bat file. I have tested it with the following branches:

git clone --branch=release/METEOR@1.12.1 https://github.com/meteor/meteor.git
git clone --branch=release/METEOR@1.12 https://github.com/meteor/meteor.git

I just checked without changing anything to dependencies and it worked as expected on Windows 10.
