Description

This PR splits pluralized strings into 2, in accordance with GlotPress requirements:
For count of 0:

# browse-page.image-no-results 
#: /components/SearchGridManualLoad.vue:109
msgctxt "browse-page.image-no-results"
msgid "no image results"
msgstr ""

For counts of > 0 and less than 10 000:

# browse-page.image-result-count (Do not translate words between ###)
#: /components/SearchGridManualLoad.vue:115
msgctxt "browse-page.image-result-count"
msgid "###localeCount### image result"
msgid_plural "###localeCount### image results"
msgstr[0] ""
msgstr[1] ""

For counts over 10 000:

# browse-page.image-result-count-more (Do not translate words between ###)
#: /components/SearchGridManualLoad.vue:112
msgctxt "browse-page.image-result-count-more"
msgid "Over ###localeCount### image results"
msgid_plural "Over ###localeCount### image results"
msgstr[0] ""
msgstr[1] ""

The last one does not need pluralization for English (it's only plural). It was, however, included here for other languages, where different noun endings are used based on the count (eg. Russian :) )
