Make 'nf-core bump-version' leave indents alone

[pinin4fjords]

Description of the bug

I see a lot of comments like https://github.com/nf-core/mag/pull/541/files#r1390783670, and consistently forget to fix my own indents after a version bump.

Basically what we'd want to happen is:

...
    nextflowVersion = '!>=23.04.0'
    version         = '2.5.0'
...

... going to something like:

...
    nextflowVersion = '!>=23.04.0'
    version         = 2.5.1'
...

... but what we actually get is:

...
    nextflowVersion = '!>=23.04.0'
    version = '2.5.1'
...

It would be good to have that command leave the indent alone and just bump the value.

Command used and terminal output

$ nf-core bump-version
