Tools: nf-core bump-version does not adjust PATH in Dockerfile and Singularity

[sven1103]

Expected behaviour:

The command bump-version (earlier release) adjusts the environment PATH for conda with the correct bumped version number.

Actual behaviour:

Both PATHs statements in the Dockerfile and Singularity file remain unchanged.

Crap, you're right... I'm sure this used to work - sorry, I must have broken something.

Or maybe it didn't actually. Either way, I'll add it now.

[sven1103]

We previously installed packages into the conda root dir, and this PATH is added by default, when installing conda. So we did not have this line :)

Ok, added - #149 not merged yet so was appended onto that PR...
