feat: add support for minor/preminor versions for custom templates

[sri-vr]

hey there,

i have added minor version support for custom templates, so that the custom templates could use it to differentiate and show accordingly (for eg font size diff for patch and minor and major) ,

kindly take a look,
thanks,

what is a "preminor"?

what is a "preminor"?

hey , its semver prelease type, see https://www.npmjs.com/package/semver#functions

for eg:
semver.Diff('0.0.1', '0.1.0');
//=> 'minor'

semver.Diff('0.0.1-foo', '0.1.0');
//=> 'preminor'

i added it here because it will be useful for tag patterns
for eg
tag 1: 1.1.0-foo
and tag 2 : 1.2.0-foo
normally if preminor is not added the minor flag wont be true and it would work only for 1.1.0$ to 1.2.0$

ah ok, so it's a prerelease for a minor bump.
