Globber exception when glob contains %

[Enqueuing]

What You Are Seeing?

When running cake from inside a folder containing a % sign in the name like:
C:\Some%2FDirectory\cake.exe build.cake
The "Installing tools" step fails with a NotSupportedException: "Unknown token"

What is Expected?

GlobTokenizer should treat the % sign as alphanumeric and allow the directory to be globbed.

What version of Cake are you using?

Version 0.15.2+Branch.main.Sha.c2ca4f7ca51c59dc9c47c9830125b4e66cf14e7a

Are you running on a 32 or 64 bit system?

64bit

What environment are you running on? Windows? Linux? Mac?

Windows

Are you running on a CI Server? If so, which one?

Yes, Jenkins. But able to reproduce locally as well.

How Did You Get This To Happen? (Steps to Reproduce)

Try to run cake inside a folder that has a encoded slash in the name: "%2F"
