dev-cmd/bump-formula-pr: replace partial version in URL
For now, restrict to partial version excluding the last part, i.e.
version with major.minor.patch will result in attempting to replace any
occurrences of "/#{major}.#{minor}/" or "/v#{major}.#{minor}/".

This should take care of common situations like GNOME, KDE, and
SourceForge URLs. It should also help with URLs like `util-linux`.

It may result in incorrect replacements if URL has partial version based
on another versioning scheme like the API version or if there are some
equivalent numbers in URL that happen to match

description <<~EOS
Create a pull request to update <formula> with a new URL or a new tag.
If a <URL> is specified, the <SHA-256> checksum of the new download should also
be specified. A best effort to determine the <SHA-256> will be made if not supplied
by the user.
If a <tag> is specified, the Git commit <revision> corresponding to that tag
should also be specified. A best effort to determine the <revision> will be made
if the value is not supplied by the user.
If a <version> is specified, a best effort to determine the <URL> and <SHA-256> or
the <tag> and <revision> will be made if both values are not supplied by the user.
*Note:* this command cannot be used to transition a formula from a
URL-and-SHA-256 style specification into a tag-and-revision style specification,
nor vice versa. It must use whichever style specification the formula already uses.
