config/remote.txt: reunite 'severOption' description paragraphs

When 'remote.<name>.followRemoteHEAD' was added in b7f7d16 (fetch:
add configuration for set_head behaviour, 2024-11-29), its description
was added to remote.txt in between the two paragraphs describing
'remote.<name>.serverOption'. Reunite these two paragraphs.
