doc: convert git tag to synopsis style

- Switch the synopsis to a synopsis block which will automatically
  format placeholders in italics and keywords in monospace
- Use _<placeholder>_ instead of <placeholder> in the description
- Use `backticks` for keywords and more complex option
descriptions. The new rendering engine will apply synopsis rules to
these spans.

Also add the config section in the manual page and do not refer to the man
page in the description of settings when this description is already in the
man page.

 	Make an unsigned, annotated tag object
 
--s::
---sign::
+`-s`::
+`--sign`::
 	Make a GPG-signed tag, using the default e-mail address's key.
 	The default behavior of tag GPG-signing is controlled by `tag.gpgSign`
 	configuration variable if it exists, or disabled otherwise.
 	See linkgit:git-config[1].
 
---no-sign::
+`--no-sign`::
 	Override `tag.gpgSign` configuration variable that is
 	set to force each and every tag to be signed.
 
--u <key-id>::
---local-user=<key-id>::
+`-u <key-id>`::
+`--local-user=<key-id>`::
 	Make a GPG-signed tag, using the given key.

---force::
+`-f`::
+`--force`::
 	Replace an existing tag with the given name (instead of failing)
 
--d::

+`--delete`::
 	Delete existing tags with the given names.
 
--v::
---verify::
+`-v`::
+`--verify`::
 	Verify the GPG signature of the given tag names.

 The default is not to print any annotation lines.
 If no number is given to `-n`, only the first line is printed.
 If the tag is not annotated, the commit message is displayed instead.
 
--l::

 	List tags. With optional `<pattern>...`, e.g. `git tag --list
 	'v-*'`, list only the tags that match the pattern(s).
