 * The Generic updater looks for well known patterns and replaces
 * content. The well known patterns are:
 *
 * 1. `x-release-please-version` if this string is found on the line,
 *    then replace a semver-looking string on that line with the next
 *    version
 * 2. `x-release-please-major` if this string is found on the line,
 *    then replace an integer looking value with the next version's
 *    major
 * 3. `x-release-please-minor` if this string is found on the line,
 *    then replace an integer looking value with the next version's
 *    minor
 * 4. `x-release-please-patch` if this string is found on the line,
 *    then replace an integer looking value with the next version's
 *    patch
 * 5. `x-release-please-date` if this string is found on the line,
 *    then replace the date with the date of the last commit
 * 6. `x-release-please-version-date` if this string is found on the line,
 *    then replace the both date and version
 *
 * You can also use a block-based replacement. Content between the
 * opening `x-release-please-start-version` and `x-release-please-end` will
 * be considered for version replacement. You can also open these blocks
 * with `x-release-please-start-<major|minor|patch|version-date>` to replace
 * single numbers
