add rpmdev-bumpspec logic

[xsuchy]

Description

Right now, the user has to implement release bumping, which can be quite complicated. It would be nice if we could copy logic from rpmdev-bumpspec. That would honor autorelease if used. And simply bump up something by one if needed.

Benefit

User does not need to study what can be in release and what should be bumped. Logic in one place.The user does not need to study what can be in the release and what should be bumped.

Importance

I have a workaround right now.

Workaround

• There is an existing workaround that can be used until this feature is implemented.

Participation

• I am willing to submit a pull request for this issue. (Packit team is happy to help!)

Note for myself:
I use this code:

def increment_last_number(input_string):
    # Split the input string into parts based on the dot
    parts = input_string.split('.')
    
    index = -1
    success = False
    while not success:
        try:
            # Convert the last part to an integer, increment it by 1, and convert it back to string
            parts[index] = str(int(parts[index]) + 1)
            success = True
        except ValueError:
            index -= 1
    
    # Join the parts back into a single string with dots
    return '.'.join(parts)

if not specfile.has_autorelease:
    specfile.release = str(increment_last_number(specfile.expanded_release))

But this failed for

Release:       30%{?alphatag:.}%{?alphatag}%{?dist}

resulting with

Release:       31%{?dist}

Note for myself, the last issue can be fixed by

specfile.release = str(increment_last_number(specfile.release))
