i think because in the second one relative to the oh group the elctron density will be more at o and p positions and so NO₂ being present at meta position will not be able to increase acidic character.....

ortho effect is considered only for carboxylic acids (like some benzoic acid derivative) and amines (like some aniline derivative)
so, we will consider only the dispersal of +ve charge by NO2...therefore, first one is stronger acid..(effect of the methyl at para is negligible)
