feat: for tag-lines, add endLines in place of dropEndLines and applyToEndTag in place of noEndLines; add startLines in place of newline-after-description rule

BREAKING CHANGE:

1. Removes `jsdoc/newline-after-description` rule in favor of `jsdoc/tag-lines` with option `startLines: 0` for "never" and `startLines: 1` for "always". Defaults now to `startLines: 0`
2. Removes `dropEndLines: true` from `jsdoc/tag-lines` in favor of option `endLines: 0`
3. Drops `jsdoc/tag-lines` rule's `noEndLines: true` in favor of `applyToEndTag: false`

 Enforces lines (or no lines) between tags.
 
+If you only want lines preceding all tags or after all tags, you can use

+be used with the linebreak-setting options of the `sort-tags` rule as both
+may try to impose a conflicting number of lines.

 #### Options
 
 The first option is a single string set to "always", "never", or "any"
 (defaults to "never").
 
 "any" is only useful with `tags` (allowing non-enforcement of lines except
-for particular tags) or with `dropEndLines`.

+necessary if using the linebreak-setting options of the `sort-tags` rule
+so that the two rules won't conflict in both attempting to set lines
+between tags.
 
 The second option is an object with the following optional properties.
 
 ##### `count` (defaults to 1)
 
 Use with "always" to indicate the number of lines to require be present.
 
-##### `noEndLines` (defaults to `false`)
+##### `applyToEndTag` (defaults to `true`)

+Set to `false` and use with "always" to indicate the normal lines to be
+added after tags should not be added after the final tag.

+##### `startLines` (defaults to `0`)
 
-Use with "always" to indicate the normal lines to be added after tags should
-not be added after the final tag.
+If not set to `null`, will enforce end lines to the given count before the

-If defined, will drop end lines for the final tag only.
